Remi, well done.
A small problem - your code does not handle games with 'Void' result correctly. For example, game ID 47707 is treated as B+R in your system. Should be easy to fix.

Thanks for noting this problem. It is now fixed.
I also optimized WHR parameters. The first version was using a parameter that I optimized for KGS data. But the volatility of pro. ratings should be much lower, and the prior stronger. So the new graphs are much smoother than before. This changes the ratings significantly:
- An Jungki was 16th, and is now 91, which looks more reasonable
- Kang Dongyun was 3rd and is now 7th. His 8-win streak did not make his rating grow as much as in the previous version, thanks to the lower volatility.
