It's not as much me being good as a few things.

1. More bad players. yes one could debate this, but the average donk who watches wpt or wsop is going to want to play nl more likely than no limit. This is just an opinion and I have no way of proving this.

2. A lot of profitability in sngs comes from good pushing with high blinds. When blinds rise so quickly relative to your stack, the limit sng does not allow for optimal stealing in the late game and the cards dealt to you affect your winrate more than they would in a nl sng tourney.

3. I hate it when i accidently sign up for limit sngs and I'm bitter about the fact that someone actually likes to play these.
