I’m not exactly sure if this is what you’re looking for but this is what I found:
“Recommended Seatpost Binder Bolt Torque Specs: 65-80 in-lbs (7.3-9 Nm)”
Hand tight should work as long as you don’t use a gorilla grip. Ti post in a Ti frame is pretty hard to damage. Keep track of how many turns and if it slips then maybe add a quarter turn when retightening…
