"For spin recovery, the operator taught the Beggs/Mueller method ..." however "The objective of the training was to prepare the student to compete in Sports1 level aerobatic competitions." so they probably wouldn't be using Beggs-Mueller for competition preparation.

Why state that?
"The ground marks were consistent with a right-hand upright spin and the following information, provided by a test pilot, indicates how the spin may vary if the controls are not held in the conventional pro-spin positions:...... However, if in-spin aileron was maintained during the recovery the aircraft could potentially enter another spin, possibly inverted, in the opposite direction." I can't see that happening if elevator actions were correct. Pitts S-2A cockpit placard "FOR FLAT SPINS USE AILERON WITH FOR RECOVERY".
"The manufacturer supplied the investigation with a flight test report for spinning. The flight test was conducted in 1971 ...". In 1980 there was a series of spin tests on SN 2219 to determine the effect of the symmetrical ailerons and spades introduced on SN 2219 then SN 2231 onwards. Detailed results are somewhat different between the two series of tests. This aircraft was SN 2225 so left the factory with frise ailerons and no spades. I've seen all variations of ailerons and spades etc on the earlier SNs. Flight manuals of the early SN Pitts were amended to include that cockpit placard.
