I did try this earlier, but in case it didn't pass the mod's.
YankeeJim: your 80 average is from the first 3 games you played as a Pro-- 40,47 and 35 (80, 94,70.)
That would be 81.33, but the 35 (70) was a par 3 round and doesn't count toward his average.
The three rr's he's now played were 47 (94) 40 (80) and 45 (90) = 264/3 = 88 which is his current average.
