IE for years, I have seen this "doubling speed produces a 70 point rating increase." I would guess that *may* be right in normal games. But I often run matches of Crafty vs Crafty, and when I try a 2x time handicap, I get *huge* changes in the win loss ratio. I haven't done this recently, but the last time I tried it, I saw the one getting a 2x handicap win about 3 of every 4... which was more than I expected... But in any case, it would be nice to see only 200mmx vs 200mmx or whatever, and stop this unequal platform competition, since it doesn't provide any useful information, basically...
