Hi there.
I am currently revisiting some SNGs and I would like to compare my performance to others. One way would be via ROI but I think the number of mistakes could be just as interesting. This could mean either as -EV play or as missed +EV play.
I would call anything anything below let´s say 0,3% a minor mistake.
Anything up to 1% a mistake.
And anything >1% a major mistake.
As default I consider anything from EG as minor mistake (e.G. a missed open raise, a bad cbet or missed valuebet or broking with AK/QQ against the wrong guy) with the exception of obv. spewplays. This part is obv. much harder to evaluate as there are quite a few different approaches possible.
Frankly i would be more interested about mistakes objectively marked by tools like Wizard in the Steal/Resteal and PoF-phase. The latter being the one where mistakes can be identified most clearly.
What would you consider a good/very good performance on average? How much of a sample of Reviews should suffice?
