I am not certain if this is a bug or if I am not interpreting these talents correctly. PPP fires 3 times, and “Each shot deals 75% damage”.

Headshot: Increase Big Shot’s damage by 75%…

At level 20, Big Shot states its normal damage as 329. With PPP alone, one would expect each shot to be 329 x 0.75 = 246.75, and testing it shows it as 247, so that looks good. With HS alone, one would expect the damage to be 329 x 1.75 = 575.75, and testing shows it as 576 so that looks correct.

But when I use both, I would expect each shot to be 329 x 0.75 x 1.75 = 431.8125. But testing the combo shows damage of 493 on each shot. I can’t for the life of me figure out how it comes up with 493 instead of 432. I made sure the target didn’t have any armor change to cause it, and specifically avoided talents that affected this damage.

I noticed that 493 is almost exactly 1.5 times that of 329. Could if be that the 75 increase of HS is being added to the 75 of PPP, making each shot 150% of base value?

I also see that 493 is almost exactly twice that of 247, which is the 75% damage value. Could it be that the 75% value is being then increased by 100% rather than 75% due to HS?

I just don’t know where it comes up with 493 for each shot in combo of these talents.
