His results were totally not expected. The probablity for him to lose 170 units in one session is REALLLY SMALL.
That depends. He didn’t mention how long his session was. I’m guessing it was probably a few hours. It is completely normal for a Wonger to occasionally have swings of 50-80 units per hour, so a $10 Wonger can easily lose $500-$800 in a single hour of play. Although a loss of 170 units is a single session is fairly unlikely, it does happen from time to time. I agree with you that it is unlikely, but it is certainly not unexpected.

When you wong you only play positive counts so your variance should be much less right?
Actually, it’s the other way around. A Wonger will have higher variance for several reasons. For one thing, they are never making minimum (1 unit) bets. If a player only plays at positive counts, their smallest bet might be 2-3 units. If your smallest bet is 2 units then you might as well double your unit size and call it 1 unit. That means that the average bet is higher so the variance rests on those few big bets that are being made.
Also, a Wonger can usually play more hands per hour because they are finding other hot tables without having to sit and wait for a particular one to heat up. They are abandoning the cold shoes and finding more hot ones than a play-all player.
On top of that, since they are avoiding all negative counts their units size will often be higher. That is because their bankroll is not being drained by losing minimum bets 75% of the time. Having a bigger advantage means having a bigger optimal bet. A play-all player might require an 800-unit bankroll to have a 5% ROR, but an aggressive Wonger may only need 400 units for that same 5% ROR. By changing his playing style, a $5 player suddenly becomes a $10 player making $20 minimum bets. He’s almost become a green chip player!
His bankroll is the same but his EV has soared much higher that he thought possible.
That is the incredible power of backcounting. The short-term variance will be much higher, but the long-term variance will be the same and the EV will increase. It’s all about leverage…
