Are you saying that the hardest rudder pedal does not indicate the yaw direction in spins? As I said, I haven't tested that proposition but I believe it to be correct and that is why I said "I think". There is certainly no light heartedness about unintentional spins implied on my part so what are you getting at?
In any case, as I read it, the accident brief you cite sheds no light on what actually went wrong except the PIC did not appear to be very experienced and the COG/WB was questionable.
Cheers
