a perfect sword mod is considered to be the all powerful 15^50 (+15% damage while health is above 50%) mod.
but does this really make any difference at all to an almost perfect mod of 14^50 (+14% damage while health is above 50%) mod?
i did some calculations to figure this out, based on a 15-22 damage sword that has been customized i worked out the damage of both a 15^50 and a 14^50. here is what i got.
----------------------------------
15-22
+15% While Health is above 50%
+20% (customized)
20.70 - 30.360
Round up/down
21-30
----------------------------------
15-22
+14% While Health is above 50%
+20% (customized)
20.52 - 30.096
Round up/down
21-30
----------------------------------
if i am correct that means that the weapons are capaple of exactly the same damage, and if there were any difference taken into account you would have to be fighting for a very long time to even have a second of difference in the average time taken to kill something.
So i call upon someone who has perhaps a deeper knowledge on the exact game mechanics to either back me up or show me the err of my calculations.
From this question being answered i hope to determine if paying hundreds of platinum extra for a 15^50 over a 14^50 is just for the "wow" factor of having a perfect sword or if, in fact, it is actually better my even a margin.
I would like to point out i have a 14^50 spatha that seems nice enough but i don't want to spend more on modding it in case it does indeed fall just short of the mark
in fact that is the whole point of asking this question in the first place.

(that includes me, although i use axes)
