It also highlighted that there can be varying interpretations of an ‘incipient spin’, and this has led to aircraft not approved for intentional spins being used for incipient spin training and assessment." Naturally, as CASA has never defined an incipient spin
About the best definition is that of the FAA in some documents.
The incipient phase occurs from the time the airplane stalls and starts rotating until the spin has fully developed. This phase may take two to four turns for most airplanes. In this phase, the aerodynamic and inertial forces have not achieved a balance.

An incipient spin is that portion of a spin from the time the airplane stalls and rotation starts, until the spin becomes fully developed.

Full forward stick??
I didn't see that said.
