Post Cherokee Arrow III (1976) MAP questions

I recently got endorsed in the Cherokee Arrow III PA-28R-201. When it comes to setting the power RPM & MAP, my instructors never really went over the table from the Pilots Operating Hand book.

Taught, Take off is Pitch Full Fine, Full MAP, then once off the ground it is both MAP 25/RPM 25. In the circuit they taught me on downwind it is MAP 21.9 and RPM 24 (Under carriage down), then turning base MAP below 15, RPM Full Fine, then bring the MAP up as required for power to touch down.

We went out to the training area (Steep turns, Stalls etc) up to 4500 feet using MAP 22.9 / RPM 24, and keep bumping up the MAP 22.9 every thousand feet you climb as it drops as the pressure drops off with height.

If there are some experienced Arrow pilots around on here, some of your experience and input would be much appreciated with power settings. (Personally I would sooner just follow the hand book table as it is much easier, it get a little confusing when the school never went near the power setting table from the POH.)

I have a mate who fly's a Mooney who helped me out with setting decent points (rule of thumbs for a given TAS and height to loose) when flying cruise as you cannot just close the throttle to lose height like the C172's, Warriors and Archers.

Thanks

Andy
