  If I've mis-judged the placement of the bights, or for really stretchy rope,

  Starting from a Clove hitch, as shown at (1)-(2), or from the initial arrangement shown at (3), there is always ample room for the two opposing bights to reposition themselves on the surface of the pole - so there is no danger of a premature terminal "closing" of the hitch, before the wraps can be pulled to the point they become maximally pre-tensioned. I have tested this "inverted" form of the TackleClamp hitch on dozens of different materials - including power and telephone cables... :). Although it is true that one can never predict with precision when and where, on the surface of the pole, their movement will "terminate", there is no need to "redress the bights back".

the more turns there are, the less effective this method will be as only the outermost turns will be tightened. 

  For 6 wraps, when tied as shown in (4), this is not true - and you can see why, just by observing the distance between the ends and the middles of the turns. Now, there is an interesting win-win situation here : if we will need more wraps, that would be because the surface of the pole will be very slippery, so the wraps would be able to slide easily on it and the induced tension will be able to reach at their middles - and if the surface of the pole will not be very slippery, we will not need more wraps !  :)

This is not a knot.
