I have a suspicion.... of course, this is all anecdotal without any scientific testing, but...
in my weeks backtraining in rockies, picking through boxes with or without armor I botch them maybe 1 in 5 times.. and every time they're mime traps..
Backtraining different weapons in maras now.. picking through boxes with armor I have yet to botch a trap...
Only stats increased was stamina from 28 to 30.. box skills raised at most maybe 4 ranks but still at the same ten's digit..
I think someone working in the back has a secret fetish for mime shows...
