I used the same relation between ELO and winrate as on CGOS
The reason why I did not plot winrate and why I plotted log(playouts,10)
is, that this seemed to be more or less linear.
The graph is made from 550 games with random number of playouts (exactly
spoken log(playouts) is equal distributed).
Than I fitted a 5th order polynom (least square)...
