I marked some hands that I played all-in (and lost) from a few of the $0.55 9-man SNGs I played today, and when I looked back on them I saw that HM2 has marked them all as +$EV. Without looking at the hands individually, is it naive to use this stat to conclude that, on the whole, I played the hands reasonably well?
I know that there are a myriad of other things to analyse... But I'd just like to know how useful you think this stat is.

Thanks
