Agreed but does that schedule now still happen at Easyjet - ?
The roster you mention was in my humble view a by product of the UK CAA early / late rules - there's plenty of scientific evidence supporting consecutive earlys / nights and the EASA makes no mention of any proposed limits because in Europe apart from the UK there are few/none.
So bringing up what happened in the past is wrong because Easyjet went a long way to managing fatigue. I have more sypathy for MIR the only question i would ask is was that schedule possible before sub part Q was introduced
