"From what you've said (which is what i imagined was the case, but wasn't sure) and counting the foxtrot music 1 & 2 & 3 & 4 & ...etc, the slow lands on beat 1, the "and" lands on beat 2&, the next quick lands on 3 and the final quick on 4."
Um, no. The initial slow is much closer to beat 2, and the final quick long after beat four. As I said, it's not simple, really it takes years to get it figured out. As a clue, don't think about when the feet arrive and depart, think about when the body moves.
This is true for a basic SQQ timing as well - the fallaway just makes it more complicated.
