somebody has to explain to me what the F the pokerEV software is trying to tell you?

for me, the blue line runs parallel to but above the red line which runs above the green line.

why do i care about showdown winnings? i can see that expressed as a % in PT.

why do i care about total winnings? again, i can see that in PT.

somebody tell me what the sklansky bucks are trying to tell me. i know its supposed to tell me if i run good or bad. but, i cant tell how.

yesterday, i ran well. today, not so much. but the graphs look the same. blue above red above green. and not much spatial difference between them when compared to yesterday, either.
