Clawing my way back to profitability

Some time ago, I concluded that it was practically impossible to make a profit playing sit and gos. With my recent good results, however, I need to reassess this. As it turns out, I've almost clawed my way back to sit and go profitability. Here are my current career sit and go results:

2    130
3    135
4    117
5    99
6    66

667

If I'd played all of these sit and gos using the $50,000 buy in, $800 entry fee structure, I would have made a profit of $3,166,400. If I'd played all of them using the $45,000 buy in, $5,000 entry fee structure, I would have lost a grand total of just $5,000. That's essentially breaking even. I find that really encouraging!
