The mile marker winches are two speed, so if you get ~20fpm in low, you'll get around 100fpm in high. That's more than fast enough for a home owner/non professional. Your 180fpm I would say is in danger territory for the non professional. Things can go sideways really quick at the speed if you're not used to it and careful.
That's a typical logging winch speed at 540 rpm. Remember that we are pulling logs, not recovering vehicles. It's also the spec speed at half spool, with 115 feet of 3/8 inch cable out; it is faster as the tree is pulled in.
Admittedly though it's a rare occasion that I ever operate at the recommended PTO rpms.
