I'm sorry if I offended you, truly. Your question has merit but I personally find when something (a step or rise or whatever) is over analyzed, it sucks all the joy out of dancing. I just watched a couple of videos of the Hiltons dancing and I'd say that his rise and fall varies from step to step yet that did not take away from the wonderfulness of their dancing.
Who do plan to teach? You say have had a long and successful amateur career and I hope you can transfer your knowledge over to a successful teaching career. If you are going to coach championship level dancers, then your rise and fall concerns may be addressed. Beginners are scared off by too much technique right off the bat and if you make them feel they can't dance if their rise is off, they will never step on the floor. Beginners are most instructors bread and butter.
I am not a great dancer, bronze level at best, but I am a good teacher. Great dancers are not always great teachers. Anyways, I wish you well.
