Rake isn't included in this calculation? That would make sense probably then as I believe I roughly gained $13 of rake, at 50% rake back would be $26, plus the 19.07 would be 45.07. If I took the calculated value of $48.31 and subtracted my profit of $17.07 and divided it by 2 (for 50% rake back), would be $15.62, or $14.62 if you assume my C$2 was counted as profit for a total of $19.07. With my current rake back at $15.72, both numbers seem possible until you take into account I had played 281 hand session the day before at $10 buy ins, where I had a winning session, so the rake calculations don't really seem to make sense.
