They played 109 games. Had they stopped at 100 games, the score at that point was 55 to 45, consistent with 30 points apart.
And had Siming just closed out the last two games from there, the 102 games would have worked out to exactly a 35-point spread. Now I know that didn't happen and instead they played 9 games from there with Donny winning those 7-to-2.
But think about how easily it could have turned out that Siming wins those 2 games. And think about how different the Monday morning story on AZ Billiards would be. Do people really want their whole view of where the ratings of women belong to be contingent on Donny closing out with 7-to-2 (what actually happened) rather than Siming winning 2 games. These swings are a ridiculously small amount of data.
Those 109 games were enough to move Chen 2.9 points. IMO, that is HUGE.
I'm going to figure out some bet for the action room and any takers, that the top 10 women will come down a bit in about 3 years time, as there becomes more and more direct coupling. I'll need a fair way to compare now and future ratings, and figure out number of movement I can get good action on
