When you pass a whole number (2,3,4) you get an additional .4 SR rating added or
subtracted depending on which direction you went.if you have 2.98 SR and earned
.06 the system awards you an additional .4 for a total gain of .46, once you crossed
over the system went back to awarding SR the normal way.
This is so people don't jump between 2.x or 3.x every couple of races and gives people
safety net for promotions.
