Yes, on a small sample size, you can definitely win some with it.
But looking at the pure stats:
At 3-max you win twice the buyin with the 2x multiplier which happens in 47.6% of the cases.
So mathematically it's a -2.4% in the long run.
Would be interesting to know how the numbers would look like with probability of higher multipliers which would ,given that you win ,compensate for that low percentage no?
I mean no format can be profitable forever .
Attention span decreases and we make mistakes.
But if you do play smaller sessions I am pretty sure the numbers would be different and can be profitable.
E.g AllinOrFold.
You will ultimately lose if you continue playing but if you got the right timing you make a nice profit.
Pros make thousands in that format lol
