We changed ours in 2021. The opening hours of the box changed and with that we were told all new rosters had to be 60hr compliant. Here is mine, it's single manned, 4 residents, open 24/7 apart from Saturday day shift is 8hrs. 4 week cycle.

I think the trick to a 12h roster is only coming off nights twice in a 4 week turn which means for a 60h roster is having a block of 5 nights. We are in the nice position of not having any GPR shifts. Yes, sometimes you'd get them off but residents having GPR built in never felt right to me, luckily management wanted to close the box for 4 hours a week which means with 4 residents we don't have spares.
