Hyper Turbo 1$ 180 players on PokerStars???
You shouldnt think in terms of how often you cash, as you could min cash alot and still make a loss a better way to look at it is ROI(Return on Investment)
ROI - Profit/Cost or Return/Cost -1
e.g. You play 100 Hyper Turbos which cost $100
Total Winnings $140 so you have made $40 profit
ROI = 40/100 = 40%
Obviously 100 game is way too short of a sample but you get the idea and 40% is way too high long term to be sustainable. Think 20% would be possible but a good target would be 5-10%
I actually played some of these before but only 44 Games
Cost Return Profit ROI
44.00 79.24 35.24 80.09%
As for original question how many times you should be in the Money?
As 27 places pay and if it was a random game you should cash 27/180 or 15%
So your targetwould be to cash more than 15%
