Even back in 2019 Thorpe were running 2 trains on the coaster most of the time - I think there's been a definite shift in philosophy there. It doesn't always mean the rides run better though (Colossus and Inferno sometimes have less hosts and so struggle, for example).
Saw usually runs less cars on off peak days, but that's rarely noticeable.
Currently Rush is running one swing, but I think (/ hope) that's more a short term problem and not standard for off peak days this year.
