Since that didn't seem to make sense as an answer, let me rephrase my previous statement:
This Gamma total hasn't worked after recently submitting new times, and (as far as I'm aware) this pattern carries on with all who have recently submitted new Gamma times.
In fact, quite a few totals (Gamma total, Sonic R total, Sonic Adventure 2 Race totals, Sonic Adventure Race totals) are askew or have improper values. They all relate to divisions being added/removed, so there lies the problem, I suppose.
