I think you missed my point. I sought out and completed UA and spin recovery training. In America "a lot" means:
How many of those occurred during training? How many occurred in Australia over a similar time? ATSB covers about 10% of the data required to objectively provide an answer. That is to say the data to identify and report on fatal dual or solo training accidents that were directly attributable to stall, spin or UA training does not exist. The query exists for the ATSB database down to single engine land aeroplane dual or solo training but the detail of each report does not specifically identify "spin training was being taught then people died". Also ATSB public records go back to about 2003 only. ICAO goes back to 2008. NTSB had woeful recording prior to 1960. Therefore the publicly available data does not prove or disprove that "Spin training at the Sport Pilot, RPL and PPL level increased the number of fatalities". One of the issues is that when people die in training accidents, its hard to tell exactly what they were trying to do at the time and ATSB don't report things that they can't point at objectively.
So ... people died in training accidents mostly in the US. Their aviation operations are roughly 10 x Australia's so when people die/d in training accidents there and make changes, people in Australia take/took note and make/made changes here. This isn't my opinion. Also I don't care if its a good idea or not. Its just what happened. People decided to change something in reaction to something else bad happening in the expectation that it was the right change and bad things would stop happening.

The same document says the NTSB and the FAA are at odds regarding spin training.
Hell of a way to start a bar fight @Manwell
