Question about +damage on bows

What's the difference between +14% damage and +15% damage on recurve bows? (I know the info is in wiki but I'm lazy to search it from there so might as well ask from here.)

1 dmg for every 100.

lets say your base damage from 4 attacks are 30, 25, 17, and 28. This totals 100.
If you have 14% recurve bow, you will actually hit 114. If you have a 15% bow, you will hit 115.

A lot of money also. One off perfect and sale price of a weapon plummets like a rock.

I thought the bonus damage is per hit that will round off to whole number

say for 30, 25, 17, 28

30*.14 = 4.2 -> 4
25*.14 = 3.5 -> 4
17*.14 = 2.38 -> 2
28*.14 = 3.92 -> 4

100 + 14 = 114

30*.15 = 4.5 -> 5
25*.15 = 3.75 -> 4
17*.15 = 2.55 -> 3
28 *.15 = 4.2 -> 4

100 + 16 = 116

Indeed. And now you answered your own question .

It indeed is per hit. I was speaking from a general sense and choosing numbers that add up to 100 so that the general point was reached. While in this particular case it was not 100% accurate, the main idea is still the same and you seem to have got the understanding.
