Do you have any current FAA documentation available that says they want stall recoveries with minimum altitude loss? I thought that went away several years back, and now you just have to recover to the same altitude you started the maneuver at.
PTS for private/commercial airplane have been superseded by the ACS. From the current FAA Private Pilot Airman Certification Standards, VII. Slow Flight and Stalls, PA.VII.A.S3 and S4. (Yes, I just this morning did the online module on Airman Certification Standards just now to renew my Flight Instructor certificates.)
PA.VII.A.S3 Establish and maintain an airspeed at which any further increase in angle of attack, increase in load factor, or reduction in power, would result in a stall warning (e.g., airplane buffet, stall horn, etc.).
PA.VII.A.S4 Accomplish coordinated straight-and-level flight, turns, climbs, and descents with the airplane configured as specified by the evaluator without a stall warning (e.g., airplane buffet, stall horn, etc.).
For Commercial Pilot, at the discretion of the "evaluator" (probably a DPE), full stalls, power on and off, may be required.
I did find a 2002 PTS on line, and in VIII. Area of Operation: Slow Flight and Stalls, B. Power-Off Stalls:
6. Recognizes and recovers promptly after a stall occurs by simultaneously reducing the angle of attack, increasing power to maximum allowable, and leveling the wings to return to a straight- and-level flight attitude with a minimum loss of altitude appropriate for the airplane.
