That is almost the identical heuristic that Lazarus uses.     But in 
addition to this the  time is loaded up front - in other words early 
moves use a lot more time - but when win-rate is high it's divided by 
something not quite as severe as 1/10 since it gradually plays faster 
and faster based on the move number.    I think it's a very good 
algorithm.      Lazarus also would speed up when losing badly just out 
of good manners - unless resignation is turned on.
