Hi Max,
this sounds like the problem lies somewhere else - adoption / MINT links.
In healthy environment MU roams between APs without significatn change to topology, hence I do not believe there is going to be much accounting.
RFDM aggregates here the stats and only informs adopter when MU changes stats.
However, if you have local (level1) adoption then it might cause little more traffic.
I'd recommend you to raise a GTAC technical case so we can understand the situation better.
Regards,
Ondrej
