Wont be able to verify any of it for a while, but here: http://www.reddit.com/r/DestinyTheGame/comments/2ja75b/damage_and_attack_and_why_you_should_upgrade_your/

Interesting, the attack/15 calculation for damage caps given fits the data here, except for the Silvered Maverick Mk. 41. That comes out to 15.333etc. and it says that value isn't rounded, so there should be a marginal increase above level 15, but there was none.
I might take some of the guns back out to try on levels 8, 14, and 16, to see if they respond as expected, and I'll probably do the calculations to check this proposed 7% increase.
preliminary look: 133*1.07*1.07 = 152.2717, and indeed the damage is 152 for the Mos Gannon III at level 4, but 133*1.07*1.07*1.07*1.07*1.07*1.07 = 199.597137, that should scale it up to level 8, and the damage cap should be level 8.666etc., but the observed damage at 10, after it stops scaling, is only 166, which it passes at the equivalent of level 6
precision damage does the same thing, 398*1.07*1.07 = 455.6702, which checks out, but 398*1.07*1.07*1.07*1.07 = 521.696812, scaling to level 6, makes it pass the observed level 10 value
then we have: 149*1.07*1.07 = 170.5901, so that group matches the prediction for level 4, and 149*1.07*1.07*1.07*1.07*1.07*1.07*1.07*1.07 = 256.009741 for level 10 scaling, with observed value being 255-- also inaccurate but I would call it close enough
I don't know what's going on here; my main two thoughts are impact is messing with the scaling or the multiplier isn't exactly 7%, and may even vary based on... who knows what, really... weapon tier? He tested with a legendary and a rare and the 149 group are all rare. I'll try to get out and get those 8, 14, and 16 numbers for the edge-case-ish guns that I haven't upgraded and see if they fit the damage cap calculation at least.
(note to self: don't do this at 2 in the morning, 3 in the morning comes way too fast)
