Depends on stakes and what format? I'm assume the $1 on stars for example..
0.92 + 0.08 I think? correct me if im wrong??
0.46 towards prizepool 0.46 for K.O ( 2 places paid 1.38 each )
I would say the average pro ROI here would be 20% however anything above 5% is good just means your ability is lower and the swings maybe longer / more swingy.
I guess you can argue if you can make a living from it then you are a pro so if you put in an insane volume and only have a 5% ROI and someone plays hardly any and has a 20% roi then the pro is the guy who is making more... but i consider a pro to be the very best players at the particular format. aka the top 5-10% for example.
I hope this helped, I use to have a 20% roi in spin n goes and when i asked some other winning poker players they say not many have better roi so I'd say i was possible the top 5-10% at spin n goes? but maybe I'm wrong and there are people absolutly crushing with 30% roi's/
sorry for the massive paragraph I hope this helped though.
