Live Regular Grade Calculation

Total Eligible Games: 0
Average Opposition: NAN
Expected Score: 0 (NAN%)
Actual Score: 0 (NAN%)

Calculation
New grade for previously graded player is given by the following:

new = old + (800 * ( act - exp) / n) + drift

1917 + (800 * ( 0 - 0) / 30) + 0 = 1917

Where new is the new grade
old is last season's published grade (1917)
act is the actual points scored (0)
exp is the expected points scored (0)
n is the higher of 30 and the number of games played (30)
drift adjustment (0), proportionately reduced if less than 30 games played
This gives a live grade of 1917
