mdenham, your math was odd... you think blau will win, so you assume lower base damage (favors blau) and higher ACC (also favors blau)? that's not convincing. but yeah, it looks like i was hasty.
Well, the highest fSTR you're going to get in that situation is 7 anyway. 5~6 doesn't appreciably change that
part of the figure, and I was lowballing the percentage at that step anyway (at fSTR 7 it's ~7.174%; at fSTR 5 it's ~7.319%).
Knocking off the minimum increase from 3A +1, this leaves Blau 5.260~5.402% ahead with acc+ and atk+ to take into account. Leaving atk+ out for now
(mostly because I'm not sure about what "average" attack for THF is; I suspect 300-330 without food, 370-400 with food), we then figure out how much base accuracy we'd need for the acc+10 on that FB to win (which is a situation that's pretty well geared to the best possible increase for it anyway, just like the assumption that there's no other 3A+ gear present).
case - which is specifically a "you're TPing past 100%" case - the FB comes out ahead as long as your base hit rate is below 90.2%. The rest of the time, your base hit rate with Blau would need to be below 47.53% instead. (Adjusted from the last post because I suspect I was doing odd rounding things as well.) And remember, we still haven't taken the atk+15 into account yet
, which just makes it worse for that specific FB.
Apologies for making it look odd originally, though; the problem was more that I'd checked things, then didn't mention "oh, hey, now I'm going to drop that accuracy bit out to figure out where the crossover point is".
