Kamelchaser,
I think your maths is correct as it seems to work out roughly the same for me, but with smaller numbers (junior F/O). Only individuals can decide if it is worth working days off for what is on offer but the fact the company have to pay us to come in on a day off should ensure more roster stability. Having said that I can see a roster coming which has the minimum 8 days off (but not more than four in a row!), 100 block hours and the rest filled up with standbys which will greatly affect our lifestyle but not cost the company anything if they don't use us. Maybe I'm just being cynical but only time will tell.
