Its one thing, to spread to 1 to 2 or 3 hands based on the number of players, but isnt there a different perspective to this? Meaning isnt there a point where you want to switch to 2 hands based on the count, not the number of players?
If I find myself playing with 5 or 6 other players at the table, then wouldnt it be feasible just to play 2 spots, full time? to make up for the lost number of rounds per hour. Alot of times you dont have the option to spread 2 or 3 hands with a full table. So why not just play two or three spots instead?
Another thing, is when playing heads up, wont speading to two hands reduce your RoR while keeping the same WR?
