An example is going into Facing Charleston where many instructors would have the follower reverse their footwork. I don't think that is the right way to handle it. I would change the entry into the step patterns such that the leader is the one to reverse their footwork. This requires one dancer or the other do a compensating step to put themselves on the same foot as their partner. I would have the leader execute the compensating step on entry and exit from the pattern.
Many instructors have the follower execute the compensating step.
Third, keep the standard count and standard footwork together if at all possible. A good example is in executing a Crossover Charleston step pattern. One instructor uses a less than optimum entry pattern which requires shifting the standard Back Charleston part of the step pattern by 4 beats. This means that what you would normally do on beats 1 thru 4 is now being done on beats 5 thru 8 creating a step pattern from hell. It didn't have to be done that way.
