From full AND to about 5 units it takes 60 - 70 turns. Manually trimming on ground is easy. In the air it’s a different story. Add 300 kts+ and it gets even worse. Not impossible, of course, but much harder.
If any of you would like to try manual trim on your next flight, remember to place the stabilizer cut out switches to OFF. That trim wheel can be very nasty if it starts to trim when you hold the handle.
