General UVHM Matchmaking: What is the lvl cap for online matchmaking?

I ask, because today I actually dared dip my toe into the public matchmaking waters since the latest patch. OP Matchmaking is working just fine ( thanks a ton ), but illustrious Matchmaker was offering to link my lvl 54 Axton to a lvl 61 game.

I don’t remember the lvl swing being this drastic pre-patch. To join that game, I potentially faced UVHM enemies spawing at 9 lvls above me. ( since many spawn 2 lvls above your character anyway )

Has this happened to anyone else, or just a strange glitch in Moxxi’s Madd Matrixx?
