(not sure if it's classic or anything changed to bs formula)
formula should be ((weapon dmg*2)+1)*(backstab skill/25)
for me with a 8 dmg mainhand and 165 backstab skill it should be ~112 dmg. it is 103 at the moment. seems the backstab/25 gets read as 6 (type int variable?) and should be 6.6 (float/double) according to safehouse rogue faq
