If you send me your OSDMap from "ceph osd getmap," I can test it against the latest code.

I'm finding the same thing. The balancer used to work flawlessly, giving me a very even distribution with about 1% variance. Some time between 12.2.7 (maybe) and 12.2.12 it's stopped working.
Here's a small selection of my osd's showing 47%-62% spread.

$ sudo ceph balancer status
{
     "active": true,
     "plans": [],
     "mode": "upmap"
}

I'm happy to add data or test things to get this bug fixed.
