You were clear but my question is... Why a reply so hard to a simple/easy to set up/difficoult understanding formula that would "waste" (very very) little computer power? Are you part of the CPU'syndicate?
When the formula will be found, programmers will need just 1 hour (ok may be more but i can bet less then 3) to set it up. But we will have a tool that could say how plays a pilot (or pirate, vampire, e.i) even if it is our fist encounter. Dice randomic follows statistic rule... So is Hardly significant.
Anyway even without this (awesome ) implement this site is great! Thanks programmers and game designers!
