Substantially closer to my front foot? This is not what i'm seeing on the Sinkinson tape, which i've just been studying in close detail. It's his teaching tape 'Come Dancing' -the slow waltz section. He starts with a natural turn and i played it frame-by-frame (20 frames per beat) to measure as accurately as i could how he controls his foot plant. For the right foot plant on 1 there is about 1/5 - 1/4 beat between the initial heel strike and the foot going flat. It would be longer than this before the weight rolls onto the ball of his foot. His body moves over the standing foot almost exactly 1/2 beat after the foot plant. The same thing happens with a reverse turn.
The detailed timing on his natural turn is very interesting though.
If my body were 'substantially' closer to my right foot (for the step on '1') wouldn't i be over this foot very early in the beat, and my body flight be curtailed into beat 2? i might try it to see what happens. However, Sinkinson doesn't appear to do this.
