i think it is the opposite. if u play 10 70-30 as favourite u win 5 and u loose 5 then ur ev(red line) would be up and the winnings(green line) would be down.So this means you are running bad.But if you win all for example then your red line would be down and your green line would be up meaning you are running good.But i can understand why if i didnt won any hand as an underdog my green line(winnings) is above the red line(ev)

Lets say we have 20 hands: in 10 of them we are 70-30 favorite and win them all, in other 10 we are 80-20 underdog and lose them all. Lets say all this happens in NL10 cash game with stacks of 10$. Now our EV for first 10 hands would be 10$*(0,7-0,3)*10 = 40$, and our profit is 100$, though EV difference would be -60$. The same with other 10 hands: 10$*(0,2-0,8)*10 = -60$, while your profit is -100$, and EV difference +40$. When we add both these to one, we get that our EV difference is still -20$, what means our EV line is still 2BI lower that winnings line.

Hope that helps
