Why does this show SB raising from 45 to 72.5 which is 27.5 and HERO calling for 30 more? Sorry if this bugs noone else but I just want to be clear. I'm guessing that SB actually raised to 75?

I have no idea what this sort of min raise usually means at the 215 but it may mean that villain is a clown, in which case not raising him out of the pot in order to get more chips from him on the turn sounds good to me.
