Hey, so I've been trying out some spin's at Winamax room (called expresso) and i was seem to be doing alright at the start but then this happened.

ChEv seems to be really good as far as from what i've heard and the ev seems to be looking good as well but is 50+ BI swings normal at the micro spins or am i just not adjusting enough and getting into way too many variance heavy spots?
