Anonymous. If one actually reads the recomended reference instead of merely name dropping. Well here it is.
At the full extent of the stride
the ball of the back foot and the heel of the front foot are in contact with the floor. Continuing to move backwards
draw the RF back to the LF and at the same time slowly lower the the Left Heel to the floor, making sure that it does not touch the floor untill the RF is level with it. Repeat. Making sure that it does not touch the floor untill the RF is level with it.
What could be plainer than that. This is the way it has been taught since the early 20's and before. If you are unable to dance this way then it is your bad luck. The secret is to use the whole of both feet from the toe to the heel. I think most will agree that the higher the heel is from the floor, the longer it will take to lower to the floor when going backwards. The lower the heel is to the floor the more likely it is to be in error. In other words it will be a right old mess, short paced and very much like a beginner. Also it becomes very difficult to keep good timing.
