I have two problems with discounting the results of older games. One is that the decision concerning what age to start reducing game results is arbitrary. The other is that the results for a game is zero points for a loss and one point for a win. While one point for a win could be reduced to a smaller value, zero points for a loss could not without introducing negative values. The alternative would then be to reduce the 1 point for a win and increase the zero points for a loss, making the results of the older game more drawish. This would distort the results of a game and possibly result in less accurate ratings. I prefer using the age filter to set a clean cut-off point at which older results just aren't included in the calculation.
