rake and $ev in ring games on HEM

I would like to know if the rake they show on HEM under sessions is for the entire table or is that just what they took out of the pots i was involved in at all tables I was in. Or was it exactly what i paid on the pots i won.


also what should the $EV column be in relation to $ column and what do they mean.

examples

....$............. $EV
+7.47......... +7.47
-3.05 ........ -3.05
-5.00 ..... . + 3.05
+5.00......... -3.05

EV is expected value so if you win 10$ but your $EV is 0$ you ran 10$ over EV.
Its just a useless stat to messure short term "luck".

It pisses my off when im under ev because then im beeing unlucky and it also pisses me off when im over ev since then im winning more then a should but less then i feel i should.
+ It doesnt take into acount set up hands ect so its just useless...


Not sure how HEM does the rake thou...
