You've gotta be careful for what you wish for with this stuff.

Guys want to get paid for the 30 hour overnight, so you get a min day. Yay! We're getting paid for sitting around!

Except now the pairing optimizer gets rid of 30 hour overnights, and instead tags a turn on to the back of what would be an otherwise commutable trip to make sure you work more.

Rigs and min days are always double edged swords. You might get paid more, but productivity sits and extra turns become the norm.

Having overlapping rigs is likely ideal.
