I'm going to quibble with the use of the term 'best' and suggest 'usually' might be more correct. (A contest of pedants, perhaps?)
Personally I hate the term 'accelerated stall' for a "stall under increased 'g'" because accelerated can be easily confused with acceleration, and thus some people use the term to mean a "high entry rate" stall - a problem not assisted by the conventional stall demonstrations in Part 25, where the dynamic stall is at both elevated 'g' and a higher entry rate - 1.5 g and 2 kt/sec, for example. So some people attach the 'accelerated' term in their minds to the entry rate, not the load factor. I don't have a suggestion for an easy alternative term though - 'wind up stall'? - and accelerated is unfortunately common usage.
