For anyone interested, I've updated my original list from the other day as there were a few out of date numbers (the majority of which haven't been particularly highlighted by service changes, or are very recent).

These changes are compared to the pre-corona virus timetables tho looking back a number of these have taken place at some point after the June changes, including some most recently in September. (I should also point out that my 'PVR's are technically not the peak vehicle requirement, as is the true meaning of the term, moreso the numbers reflect the standard daytime requirement.)

The Q1/Q2 has decreased by 1 to 12
The 93/94 has decreased by 1 to 6
The 58 has decreased by 1 to 7
The 10 has decreased by 1 to 6
The 309/10/11 has decreased by 1 to 15 (and no longer interwork)
The 20 has decreased by 1 to 16
The 56 has decreased by 2 to 11
The 60 has decreased by 1 to 7
The X1 has decreased by 2 to 12
The 21 has decreased by 2 to 14

And of course the X22 has returned with a PVR of 2
