Here's a slightly different view of the data, FWIW.

I computed World OPR rankings based on Week5 data only, Week4 data only, Week3 data only, Weeks3&4 data only, Weeks3,4,&5 data only, and Weeks4&5 data only.

Results:

Weeks           624 Rank

5 only            3
4 only            N/A
3 only            3
4&5 only          4
3,4,&5 only       6
3&4 only          9

So yeah, Team 624 is doing quite well.
