Average score is the average number of points you were awarded in contests.
Average win score is the average number of points you were awarded in contests when you made the money.
This last stat can be useful when comparing across a cohort. Let's say you have filtered your data down to head-to-head contests on DraftKings, and you see that on Sundays, your average win score is lower than contests on Saturday. This suggests that Sunday contests have been easier to cash in.
