Breaking makes it look more obvious that you're botting, believe it or not.
All breaking is designed to do is make random events less frequent while you bot.
So you trade the possibility of failing randoms more frequently for the possibility of looking more like a bot.
The only real difference is that you don't get XP while your bot is breaking.
Honestly though, I've 24/7'd for months on end on some accounts during mass bans, and gotten away clean.
My only recommendation really is not to use powerbot, or as I prefer to call it: powerban.
