about me

Website developer at the EBU. I used to be a fairly serious player and had a couple of successes, but I don't play very much any more.

England trials - success for BW members
One thing worth flagging up is how the top four pairs all contained players who are... I hesitate to use the word "young", but certainly young in a bridge context - 40ish or below. And in stage two of the trials it was the top five pairs. Could be the start ...
England trials - success for BW members
They went up a small amount - less than half a percent on average. No reason not to think that's because they've improved in the last two years, though. After all, the ones who didn't improve might be less likely to make it this far, so there's ...
England trials - success for BW members

Rating Study from ACBL Tournaments
For what it's worth, the NGS partnership grades are extremely close to the average of the two individuals. The mean difference is around 0.6, and something like 96% of them are separated by less than 2.
Rating Study from ACBL Tournaments
I don't know if I'll change your mind, and I can't speak for how things would work in other markets, but the experience of the EBU has been positive. The NGS is very popular here, and there certainly hasn't been any big drop-off of players since ...
A better rating system
"I can not help but believe that it's possible to improve over these sorts of naive algorithms." I'm sure you're right, Richard, and I certainly defer to you in the realm of data science, but do you really think it could improve by enough that anyone would ...
