I don’t recall getting such low minimum loot percentage on any other creature in game, this constantly.
I scan my screen a bit like an instrument panel, and watch my shots left go down and then my loot add itself to the total in the loot window. It was harder to see in the old days before we had this info on screen, so I looked more slowly and carefully per mob back then, but the ranges have stayed the same. The range on almost everything that just takes 5,6 or 7 shots usually is from
20%-120% on non-multis.
The first multi used to be at 3.5x lower limit, but some mobs now have 2x or so.
Anyway, if I know a mob has only cost me
a ped to kill, it's quite clear that my loot sometimes only goes up in the
20s pecs, or a 5 pedder cost that only gets me a shaving above a ped returned.
If it's one-shot killing at
15 pecs (yes I overkill 20hp quite a bit sometimes), then it's also clear if I get
3.x pecs back, and I can do that at a pretty fast rate, so I might mix it up by watching my 10-shot returns or whatever (might include a failed shot or two, but if the 10th lands a hit then loot is still loot, regardless of 10 or only 8 mobs). On a poor bunch that can also be only 30% over those 8-10 mobs, not commonly, but perfectly possible.
It's very low stakes, but like dice rolls between 1 and 6, except I see 3-18 pecs added to the loot total per mob, so 45 pecs for 10 shots or so is 30%, the equivalent of throwing 1s, 2s and 3s over ten rolls.
Another way of watching is to have loot notification on in chat, but is better for quick scanning if only a mat or two plus shrap each time.
Personally I got the impression that the lowest asteroids were giving me more low range non-multis, not an even distribution of non-multis (loot notification usually on for roids, by the way). Getting a 3x-ish multi thus didn't boost me from 70% up a bit, but merely got me to into the 60s. I know I need 5x, 10x multis and beyond before trying to estimate any longer term returns, but as I was getting too far behind, I reckon the ranges have been fiddled with.
Crafting, by the way, has ranges within the non-successes that can be clearly seen as grouped. You can easily take 1k clicks and sort by returns and see which percentage groups exist there.
