The only thing that will fix resistance to timing changes is practice and experience on the part of the follower. I too struggled with non-standard timing in tango and foxtrot during my early days in those dances. The more time you spend following, the more adaptable you become to deviating from slow-slow-quick-quick (or slow-quick-quick, depending on what you were taught first) and T...A...N-G-O. If you are leading a beginner, I would say to just stick to simple steps that have little or no non-standard timing. And for WCS, I actually have a much harder time breaking out of the walk-walk, triple-step, triple-step timing. Lindy timing is very very hard for me to follow. And forget walk-walk-walk-walk... sometimes I just need a verbal lead. Again, simply not enough time spent actually following that dance.
