Re: Stealth Mathematics
according to RPG.net its the average of the dice without rerolls, divided by one minus the probability of a reroll:
OEbar = Xbar/(1-p)
= 25/(0.75)
= 29ish
however, the bigger your dice get the longer the tail on the probability curve gets and the more skewed your result is. it's rare to get a reroll, but when you do it makes a big difference.
