Because my partner and I are both huge nerds we both spend a lot of time in fandom. While neither of us are entirely gender-conforming in this regard, it's fair to say that she tends more to girl-fandoms and I to boy-fandoms. But she draws 40k fan-art and is a huge Infinite and the Divine fan and I have an Ao3 account, so we both have a bit of knowledge of what The Other Half are up to, allowing us to compare notes. And, cliché as it is to observe, we both agree: the old adage is quite simply correct that boy-fandoms, and only boy-fandoms, are obsessed with power-scaling. What is power-scaling, why the gender-gap, and how do I relate to it here?
Power-scaling is when you try and work out the answer to "who would win in a fight?" or "who is more powerful?" comparison questions in a fictional setting. Of course the nature of fictional settings is that there aren't really hard-and-fast rules, meaning there's lots of debate about this sort of thing. Since these will often involve fights that did not actually occur in the official sources about the setting, or if they did were interrupted or in some sense obviously uneven or unrepresentative in some way, there's lots of room for debate. Fandoms thus often try to create rules or principles which can be used to settle these - here's a nice guide to the sort of thing people do here, though it is not always plausible in my opinion.
Now while of course it's not like there's a 100% gender alignment in who does and does not engage in power-scaling discussions, on the whole it goes as you'd expect. Fandoms which are male dominated have far more of these conversations than fandoms that are female dominated. And on some level it is sort of obvious why boy-fandoms end up with more of this: there's a gender difference in who likes fight-y things, and power-scaling is naturally more interesting in a setting generally orientated around combat or battles or martial competition. That's true! But there's still a bit more to the gap than this, because even in fandoms which do have a lot of women and which are very combat heavy (think of a lot of young adult fantasy, or the Song of Ice and Fire/Game of Thrones series, or even the recent She-Ra series which was a kind of pastel coloured war epic) anecdotally it seems these fandoms still do less power-scaling. So even when you have women invested in a combat-heavy fiction and its setting, in their fandom activity you don't see as much of this. Why is that?
My current guess is based on this Tumblr post. There's a kind of person (and I think it skews male) who "approaches stories as a collection of facts. To them, the way that they would relate to a story is the same way that they would relate to a dictionary.... to them, a story lives or dies on whether the facts are interesting facts. And when a story is focusing on anything else, it's wasted time." And it turns out that among the interesting facts are not just those presented by the story, but also hypotheticals or counter-factuals the story world suggests should have a determinate answer but does not actually address. This touches upon, I believe, quite deep matters in philosophy of fiction, because it involves seeing the world of the fiction as somehow more than what's on the page, as a realised location which settles matters even if they are not directly addressed and thereby establishes truths which can be discovered and known by a discerning fandom. Why, if I am right, this habit of reading and way of understanding fictional worlds skews male - I do not know. But I think it makes sense of why power-scaling seems more interesting to boy-fandoms: they're more invested in working out and coming to know the comparative power level facts, simply because they are generally more invested in coming to know all the facts.
Why do I raise this on my Warhammer 40k fansite? Well partly because 40k just is a very male-dominated fandom. Exactly how male dominated is a bit hard to get a read on: from this thing which purports to analyse website traffic I find about a 27% female - 73% male gender split for WarCom at time of me writing this post. But presumably that's not all hobbyists and will include (e.g.) parents buying stuff for their children. Whereas when I look through Reddit and forum posts of people reporting their experience in the fandom the popular guesses seem to be somewhere between 5-15% women, with most saying that in recent years there's been an increase in the proportion of women. (For what it's worth my own guess is that estimates based on fan-experience slightly under-count because women are more likely to be involved in the painting and reading section of the hobby, which by its nature is less visible than playing in public settings like tournaments or game-stores. But I would also guess that the WarCom site is getting a lot of disproportionately-women-who-do-the-birthday-present-buying visitors, so that will overcount. So put me down in the 10-20% guesstimate range I suppose.) In any case, what this all amounts to is that as a literal wargame setting with a very male fanbase you basically can't avoid power-scaling discussions in 40k, and despite not finding them intrinsically all that interesting I see a lot of them.
Not, mind you, that I am totally unintested in power-scaling. As I mention on my Themes page, I'm very interested in world-building as part of my hobbying. This requires there should, after all, be some constraints the fiction sets for that to work. I am not so far gone as to think there's a real fact about whether Superman would beat the entire Green Lantern Corps in a fight, I do think that if Superman loses a punch-up to some random mugger in Metropolis with no explanation as to why - that's immersion breaking to the point I don't know what the setting is trying to do anymore and wouldn't find it satisfying to try and build within that world. But also: while I do this far far less than what I think is normal for 40k fanfic, at least sometimes I am writing stories with fight-scenes, so I do need to have some sense of how they'd go. I'll say what I do below, then end by trying to draw out my personal lesson for how to do power-scaling.
So far I have basically tried to borrow from sources which I think are cool. Usually "official" sources, but not always; the Retributors from the excellent Astartes short are, after all, a fan homebrew project chapter that was only recently ascended just because the material was so popular. From this limited subclass of sources I gather together claims or ideas that I think can be useful heuristics for making my own scenes. So, say, from Fall of Cadia I gather that (Khornite chaos) Space Marines expect to be able to take only 1 casualty for every 50-100 Guardsmen killed, while it is pretty disastrous for them if they are losing 1 for only 30 killed. That said, if a relatively small number of guardsmen are properly equipped they can put up more of a fight; so we do see in some sources that anti-tank weapons, or, like, actual tanks, genuinely slow Space Marines down, even if the astartes can stil emerge victorious from such fights.
Whereas we get this from the excellent Spear of the Emperor: "To fight fair would see < the chaos aligned mortal human > forces crushed, but these men’s masters had fought Space Marines before. They commanded their minions to abandon the firefights and bring the Spears down through misplaced valour and sheer weight of flesh. Just as the bane of ironclad knights on Old Earth had been swarms of peasantry armed with pole-hooks dragging the men from their saddles, Space Marines too could be overwhelmed through sheer numbers. It was madness to look upon, and yet it was the only gamble that had a hope of working." By way of contrast this book also gives you a truly harrowing - one of the best combat scenes I have seen written in a 40k story - depiction of a small number of highly elite and augmented normal humans fighting a single astartes, and just how incredibly difficult this is even for them when it is very specifically what they have trained in and specialised for. (One of the (otherwise really well-written and fun) Guant's Ghost's books also does this, but I didn't find it as satisfying precisely because one felt the plot-armour of the main characters protecting them a bit too powerfully.) So Spear of the Emperor especially has inspired my take on mortals would fight Astartes, since it's so relevant to my setting. If "swarming in a mad rush" is actually the best plan available then people coked up on Khorne juice are ironically very well placed to deploy effective strategy here.

This is actually official art nicely illustrating the idea! Source.
Talking of which, a number of sources make it pretty clear that one thing that really does change the odds is access to warp shenanigans. A mortal human who also happens to be a powerful psycher can more than keep up with the Alpha Legion boys in this fun story. When we see Space Marines struggle and die it's often because they are taking on beings with daemonic or chaotic-divine "blessings". Finally, one thing I took away from this interesting story (which I shall write my own review of later) is that when experienced primaris-marines fight experienced Khornite berserkers one-on-one it seems that the Khornite has a slight edge; further suggesting that, in an otherwise fairly even straight-fight, being boosted by the warp really is a significant advantage.
So there you go, that is what I use for power-scaling myself. Picking sources literally based on "what I find cool" I have a rough sense of how many Astartes a competent commander expects to lose for fights with Guardsmen, a crude strategy by which Guardsmen can try and make the most of their numerical advantage to come out on top, and some sense that warp-shenanigans can powerfully mess with the general rules of thumb here. To my mind this is the level of detail at which power-scaling is useful. There's no point in trying to exhaustively collect all the facts: because there aren't any, and in any case that might interfere with the all important rule of fun that should be the ultimate decider here. Rather than seek some consistent answer that makes sense of the entire canon (which I do not think exists) just pick themes that make sense to you as an author and allow for cool and fun scenes, and then try and work out what would interfere with these rules of thumb so that when you want to break your own rules you can do so in a principled way.
