How you're calculating his record, if he does not tell when he's posting how much that "U" will be compared to his bankroll (as a % for example)?
He never said something like ............my U = "x" part or % of my bankroll
To Win 1U each pick, simple as that.
If you lose a -200 pick, you are down -2U, if you win it you are up +1.
And if you want to follow or not, it's up to you, not a problem.
If you have 45-20 WL and 30 Winning Picks are between -150 and +105, I don't think there would be any money management that would let you lose money.
