Add option to use Glicko rating system #1

Closed mwiens91 closed 5 years ago

mwiens91 commented 5 years ago

Currently fooskill uses Glicko-2 rating, which is great when you have rating periods with lots of games (~15 per player per rating period). However, when the number of games per rating period is relatively small, Glicko is slightly better than Glicko-2 (according to Dr. Glickman).

There's no reason to remove Glicko-2 from fooskill, since it's already implemented, but there should be an option to use normal Glicko instead, since this is more appropriate for some systems as discussed above.

Implemented Glicko. Need to update docs with this information, but otherwise done.
