I'm a big fan of AllAccess but, I did have a LOT of buffering - especially - Sunday.
In fact,having recently switched back to Comcast, I've been enjoying speeds from 75 to 110 MPS. Sunday afternoon I did several SpeedTest.net tests and they ranged from 5 to 30. Very Strange.
PS: For the previous year, I had Frontier with fairly consistent 20 MPS and never had a problem with streaming (other than YouTube in the evening).
