Noted the change in rating performance for the data I had. What it showed was as computers get faster the change in rating from a doubling get less and less. So from my data I calculated how fast a P II would have to be in MHz to only gain 2 to 5 elo points, if its speed were doubled. Based on my limited data. Now remember this is for a computer playing chess at 3 min a move. If a P II 93000 only played at one sec a move then a doubling would gain more points. The same way as it does today. The faster the time control the more rating gain you will get playing a slower computer. Example PII 300 Vs PII 266 playing the same program. At 3 min a move avg. The ratings gain from a P II 266 to a P II 300 is next to nothing. If you played them at 1 sec a move avg. The gain in ratings because much more. I don't claim this will be accurate. As the data was made with many chess programs old and new. But I think it might be somewhat close. Don’t take this too seriously as it was done in fun. The formula was based on the data. Noting the change in rating to the change in speed of the computer. On a doubling at 3 min a move. >>It may not be right.
