Match Scheduling

Unsure how this works at districts, though, but I presume the algorithm is the same.

The same scheduling algorithm is used in Districts and Regionals.
I don't think your description of the algorithm is correct. The cost function at the core of the optimization procedure prioritizes minimizing repeated alliance partners over repeated opponents. Time between matches is not part of the cost function at all, but the algorithm only considers solutions that satisfy a minimum match separation.
After generating the schedule the FMS provides overall statistics, which in my experience at District sized events does typically show the maximum number of distinct partners for most teams.
