I guess this is true for any activity requiring thinking. There must be a floor, a minimum frequency or total number of time practiced, but no specific ceiling or linearity between the time/frequency of practice and the progress in the art. If we had two pictures, and asked to guess which photographer takes 80 pictures a day and which takes 200, it would be a tough question. I see the above point the same way, past a certain point the number of games shouldn’t make a difference.
