The FargoRate optimization uses all the games but pays far more attention to recent games. The really old games are for all practical purposes ignored. We can still estimate the performance in 500-game chucks, though. You can see that for Morra--you're going to estimate a little below 800 however you treat old games. The fluctuations are larger than any actual drift. Here are a dozen years.How many of those 22,000 games are actually used in his fargo rate calculation? I'm pretty sure there is a time decay in the calculation.
