Use average bestMoveChanges across all threads #2072 The current update only by main thread depends on the luck of whether main thread sees any/many changes to the best move or not. It then makes large, lumpy changes to the time to be used (1x, 2x, 3x, etc) depending on that sample of 1. Use the average across all threads to get a more reliable number with a smoother distribution.
