Spyder - you really like to complicate things!
There are two schools of thought to obtain canter - simply and for the best result and as taught to me by my instructor - trained at Spanish Riding School - and what I've been teaching for 40+ years, that the outside leg back and used asks for canter and identifies to the horse the leg required to start the sequence of canter.
The inside leg always drives the horse forward and once in canter the inside leg maintains the quality of the canter.
Duffy Duck - sequence of legs is
Outside hind, Inside hind & outside foreleg together, Inside foreleg, period of suspension.
