Holdem Manager question - $ EV and EV $ Diff
I understand what expected value
(EV) is, but how is it calculated here, and what does it mean? Is Holdem Manager basing it on my hand values compared to known hand values of other players? Is it good or bad that my $ winnings are (slightly) positive overall, but the $EV is negative?
In the top section, in my second session on 11/11/08, my $ was $9.31 and my $EV was $9.31, so they were the same. Does that mean I won exactly as much as I should have won based on hand values? And for my first session on 11/09/08, my $ was $5.23 but my $EV was much higher, $12.36. What does that tell me, that I should have won more than I did? Similarly, what about sessions in which the $EV is a higher negative value, such as the second session on 11/18/08? I had a big losing session with $ at -$41.58, but the $EV is listed as -$73.35... is that telling me that, based on hand values, I should have lost more than I actually did? And what should I take away from that information? I got lucky or played well enough not to lose more?
In the bottom section, I understand that the Equity % is my chance of winning the pot after getting all in. How is the -$41.29 EV $ Diff calculated, though? What exactly does that figure mean, other than that I should have lost money on that hand?
Please try to just ignore my abysmal $0.17 an hour overall win rate.
