We are now attempting to enforce a center at 1100 (tentative, may move
to 1200 later) by increasing points gained for winning and decreasing
points lost for losing below that. This will make a user with equal
wins/losses higher than a user who consistently loses.
The other change is to scale K down at higher ratings. >1400 now uses
K=40, and >1600 uses K=32. This is a really conservative scale, and
we might make it less conservative later.
STAY TUNED!
COMING UP NEXT: rating decay
This moves most of the logic of action.php into a separate file
lib/dispatcher.lib.php and separates the actions into ladder-related
actions and non-ladder-related actions. This is intended to make it
possible to have a second action.php that handlers only ladder-related
actions, which can run on the main server computer and allow
that computer to make HTTP requests to `localhost`, which should
help reduce ladder errors.
