"None of the technique books are directed to Social Dancers."
Actually they are, in that they are specifically for the training of teachers who would in practice primarily work with social dance students, hopefully ones who are serious about learning. That was true when they were written, and it's still true today.
"So I would say you can remove the crowded floor syndrome"
Okay, so forget the infamously crowded first round at Blackpool and imagine we've somehow magically gotten a by to the later ones.
"Or a Waltz that is not played at the correct tempo."
The correct tempo varies with the purpose of the dance. 26 can be correct. 34 can be correct. The range for competition is narrower, but competition is not the only reason for dancing a waltz, even for competitors (shows for example are often a bit slower)
"Or how strong the dancer is."
Now you are showing the complete lack of thought you have put into the question. What ultimately determined the foot rise that can be used while maintaining security and balance? The strength of the dancer's feet. Even amongst "good" dancers this varies. And it also depends on what shoes you are wearing - a shoe with a stiffer toe box (perhaps because it is new and not broken in) will let you go higher.
That's the amount that can be used. The amount that should be used is an application-determined question, that depends on all those factors you insist on ignoring.
Or consider your outrageous suggestion that while men's shoes and ladies shoes might start you at a different ankle angle, you should end up at the same one. If you start at different angles, but end at the same, then that means that the ladies must use less foot rise than their partners, even at low overall amounts of foot rise. How much rise should be used probably varies for the forward or backward partner, but to state a rule which forces the lady to always use something 3 cm less foot rise change than the man is pure ignorance of the obvious fact that the appropriate amount to use will depend on many factors in the dancing.
