It was worse when MML introduced them as 4-cars though surely? 50 First and only 126 Standard.
Maybe worth pointing out that the MC coaches in 222101-4 as originally formed as 4 cars had less first and more standard seats than the 5 cars' MCs (basically, 2 window bays for 1st on the 222/1s). When 222103 and 4 received a MF from a 7 car these were placed next to the DMF. The 1st in the former MC was totally declassified as were the seats in the MF so as to correspond with the seating layout in the 5 car MC.
Although probably a first world type problem, the 1st in the 222/1's MC was of a lower standard than in the 222/0s without curtains or spot lights - possibly the MCs were MS with Hull Trains???
In the former 7 car sets the MF retained (next to the DMF) is similarly declassified st one end.
Declassification only consists of removing the 'FIRST' label from the window (sometimes a window the real first doesn't have this either) and altering the yellow band.
Possibly with hindsight detail you didn't mind not knowing
