The proper torque is enough to keep the post from moving under your weight while riding over whatever terrain you plan to ride on....without exceeding 50 kg/cm.
Use carbon paste and start by tightening to 25 kg/cm (@ 22 lb/inch), then check for movement. If movement is detected then tighten to 30kg/cm and recheck. So on an so forth until the seatpost is held solidly.
