You do partly misunderstand me.
The turn itself is wholly accomplished on the LF. The footwork is TH, but heel lowers earlier than a normal back step. The turn commences on the ball of foot, but continues and finishes on the heel. However, there is no T release (because the next step will be LF fwd), so the majority of the turn is made with the foot flat, but with a backward weight distribution (ie the foot turns around a point under the heel, not the ball of foot): this is where I suggest the 'right balance' is found by feeling the weight to be over the instep, rather than the very back edge of the heel. As the LF turns, the RF is drawn back, with the H in contact with the floor, but the pressure required is limited, and does not amount to divided weight - this is why you shouldn't be wearing out the edges of your shoes.
The weight transfer between LF & RF only occurs after the turn has been made: if you think in terms of a normal heel turn, the RF will not complete its close to the LF (assuming a R turn)until the turn itself if complete. On weight change, we often rise, but in a heel pull action we are usually 'down', and stay there. Footwork for the RF will be H to i/e of foot to flat foot.
Does that help?
