Daily average rides are just that: averages. Points are determined by how many miles you ride inside of the given league games. Each mile is a point. Averages have nothing to do with it, they're just a statistic. Not even sure why they're there.

EDIT: I just found out something curious. I did a recreational ride yesterday, and I was wondering why it wasn't counting towards the league. Turns out I forgot to tag it.

Don't forget to tag your rides, kids. A ride with no tag won't be counted towards leagues.
