If I remember good - it's random from min/max skill writen in podbot.cfg , but...Unfortunally for fillserver this parameter is taken once - so it means all bots added by fillserver have the same skill (this random is calculated once - before calling the function of creating bots table). For me - as a normal user - it's a bug (every bot should have its own randomly based skill), but for coders here it's how the function creating bot table works and they don't see the reason to change (fix) it.
