That's 3-4 days for me tyvm.

Downsides: rotating schedule, 10 hour days occasionally require working 5-6 days in a row pending when people take time off. We set it up so there are overlap on a schedule in the evening though, so you also have to work a abnormal shift ~4 times every two months.

I'd still prefer it over 8x5s. Those long weekends are glorious.

8x4s is what I'll be pressing for when I can.
