Hi Howard,
          Think of your coil being formed like a screw thred, (helix) if
the first or uppermost layer of the coil passes half way thro' the
becket hole, and assuming the pin is left to right at 90 degrees to the
pin block, you will form the tighest possible coil, and obtaining the
best stability. If you take the discussion to the nth. degree then some
variation should tke place to compensate for the difference in the
thickness of wire.
