    I just tested both approaches separately. If I leave the STAT_THRESHOLD at
    32 and just add the STAT_THRESHOLD / 2 trick we can scale cleanly up to
    160p in the synthetic test.

    I have a bad feeling though for 512p 1024p and 4096p with the static
    approach with STAT_THRESHOLD /2 but it will take some time to get tests
    done on those.

    I think the best right now is to just take the dynamic threshold patch. I
    expect that to do just fine at the higher numbers. If we have more trouble
    at 1024p then maybe try STAT_THRESHOLD/2 before going to
    aggregate counter consolidation.
