It's possible that a recent version of tsh does not compute
acceleration points correctly. I have been rewriting the
ratings estimation routines for tsh to exactly match the NSA's
calculations (including esoterica such as the feedback bug:
did you know that whether or not you receive feedback points
contribute to acceleration points (and therefore to other
feedback points) depends on the position of your player number
in the roster?), and building in support for three additional
ratings systems (Australian, German and WESPA), and will have
a new version posted and tested in time for this weekend.
