Knowing that normal category airplanes were tested to one turn or 3 seconds of a spin did they assume that it was OK to do an incipient spin up to one turn?

Those FAA documents and your AFM only mention stall recovery and spin recovery - nothing in between. My simple view is that if you intentionally put the aeroplane in a situation which requires the spin recovery procedure then you have intentionally entered a spin. i.e. a spin is a spin.
EASA is working on their UPRT requirements and they have defined an incipient spin in that context:
"Incipient spin’
refers to a transient flight condition in the post-stall regime where an initial, uncommanded roll in excess of 45° has resulted from yaw asymmetry during a stall and which, if recovery action is not taken, will lead rapidly to a developing spin. Prompt recovery during this incipient spin stage will normally result in an overall heading change, from pre-stall conditions, of not more than 180°.
‘Developing spin’
refers to a flight condition in the post-stall regime where the aeroplane exhibits abnormal, but varying, rates of yaw and roll, together with changing pitch attitude, following an incipient spin but before the establishment of a developed spin. A developing spin follows an unrecovered incipient spin and will usually persist, in the absence of any recovery action, until a developed spin ensues.
‘Developed spin’
refers to a flight condition in the post-stall regime where the aeroplane has achieved approximately constant pitch attitude, yaw rate and roll rate on a descending flight path. In transition from a stall with significant, persistent yaw, with no recovery action, to attaining a developed spin,the aeroplane is likely to have rolled through at least 540°."

I look forward to CASA's further advice on incipient spin training. Further to what current advice?
