I noticed my stable ranking was a bit weird a while ago, didn't think to bug report it until I noticed my stable ranking actually dropped into an even lower bracket after some recent updates.

My stable is currently in the young stable bracket, a 30k+ fights stable grouped together with all the 50 fights or less stables.
Bloody Tigers also seems to be in a strange place in the Established stables bracket, another stable with 30k+ fights in the 50 fights crowd.
