The average gives an adjusted and IMO more accurate portrayal of actual robot contribution over multiple matches, rather than cumulative score, where one magic match can boost a team's ranking beyond their typical performance.
Consider this scenario:
Last match of qualifications:
Team A: Average Score:98pts/match
Team B: 100pts/match
Team C: 102pts/match

Team D: 98pts/match
Team E: 100pts/match
Team F: 102pts/match

Seems like a fair match-up right? but the stars align for team A-B-C and...
Final score:A-B-C 300 | D-E-F 100

Even tough these teams were identical in their stats team A-B-C pulled out a significant win. The average scores of team D-E-F stay approximately the same, and while the teams were tied in the standings before this match took place teams A,B, and C are now all ahead of teams D,E, and F.

My point being: since the same number of qualification matches are played (excluding surrogates) why does averaging matter?
