I am trying to work out the damage for my demon hunter so I can better assess the effect of +CHC or +IAS etc. but I can't seem to get the figures the game tells me.

My DH has 223 base dex. with 15% CHC, 50% CHD and +20% damage as a mod. I have the two Danetta's set bows, one has 576 damage (actually 575.72007 to fit the results), 1.60 attack speed and 178 dex with an 80% CH damage jewel. The game gives it 6617.87 damage on its own. This fits with 575.2007 x 5.01 (dex 223 + 178 a base 100) x 1.6 (attack rate) x 1.195 (CHC 15%, CHD 130%) x 1.2 (mod from passive skill)

The second bow has 612 damage (or 611.97984), 182 dex. and 176 CH damage. The game gives it 7945.30 damage: 611.97984 x 5.05 (dex) x 1.6 x 1.339 (CHC 15 CHD 226) x 1.2.

If I put the two bows together I get damage of 15553.27 (All this is with no other equipment on btw). My multipliers are 6.83 (dex), 1.6 (speed), 1.459 (crit. hit) and 1.2 (passive skills). If I divide the total damage of 15553.27 I get what should be my base damage as 812.91378.

My problem is I can't see how the game gets to 812 base damage from 2 bows, one with base damage of 576 and the other with 612. It seems to me it should be 594, being the average of the 2 bows.
