Do you really believe reservists are only held to cover for sickies and emergencies, and not for flexibility for regular roster cover in addition?
I think the best way to judge crewing levels would be to see if the regularly rostered crew are flying significantly less than the productivity target or getting more days off than usual. Haven't heard any of that.
With all of the variables and vagaries and tinkering with CRS I doubt getting Christmas off (or not) will prove much. Good luck!
