JQ love assigning everyone 74.9 hours and minimum days off. It seems to be the sole metric By which they roster.
But, By the time you throw in a few standbys (always called out) and an AV day, maybe a day off payment cause you want extra $$ and minus sick day or 2 because your roster is unsustainable or you got nothing you bid for you provide end up with 80ish. Peak periods can easily be rostered in the high 80s and end up in the high 90s.
