Does a left spin differ from a right spin for a single-engine propeller aircraft, in terms of spin characteristics & ease of recovery? Given a single-engine propeller aircraft with its nose-mounted propeller rotating on the right-hand side when viewed from the cockpit, and given the typical effects like P-factor, prop-wash and gyroscopic forces associated with the propeller - 


Would there be any differences between left-hand and right-hand spin modes? (Differences both from the physics perspective as well as perceptional difference from the pilot's point of view. For example, the differences could be there from a theoretical perspective but minor enough that the pilots can ignore them in real life).
If the answer is yes for Q1, which side, in this particular case, would have a more severe spin in terms of spin rate, loss of altitude and so on?
If the answer is yes for Q1, which side, in this particular case, would have a harder recovery compared to the other side?


To reduce variables, let's assume there are no asymmetries in the aerodynamic configuration which may make the aircraft favor one direction over the other for  spin and we are only considering the effect of propeller-rotation-direction-related effects on the spin.
Chipmunk, left-handed engine: Spinning to the left, recovery takes 3/4 turn, spinning to the right, recovery takes 1/4 turn. In either case, descent rate is 6000ft/min, so not affected by the airflow direction.
