Optimizing Thief-based Xenon, interpreting calculations, & other questions

The idea of comparing relative increases seemed like an effective indicator for which items to pick and choose from (especially when considering the limited stock of certain %items and their wildly divergent prices), which I believe is most important. Although this method fulfills its purpose in the example above, would it not be safe to analogously interpret my findings in this manner? Maybe it's because I consider "%stats-to-ATT" to be synonymous to "%stats-to-actual damage"; can this way of seeing things lead to a misleading conclusion?

%stat:atk should lead you to the same conclusions that %stat:dmg does.


But if you want to compare things directly to damage, the equations might end up looking something like...

Amount needed to double damage

Attack: TotalAtk / %Atk
Atk%: TotalAtk / pAtk
All%: (TotalStr+TotalDex+TotalLuk) / (pStr+pDex+pLuk)
Stat%: (TotalStr+TotalDex+TotalLuk) / (pStat)
All: (TotalStr+TotalDex+TotalLuk) / (3+%Str+%Dex+%Luk)
Stat: (TotalStr+TotalDex+TotalLuk) / (1+%Stat)
bStat: (TotalStr+TotalDex+TotalLuk) / (1+%Stat) / MW
Boss%: (1+%Total+%Boss)

And after that you can divide them by each other to figure out everything you could possibly want to know, since all of those will lead to damage doubling.
