I mentioned earlier that if I lengthen the overall length of the 1/2 wavelength vertical that its polarization flips, and in my models I seem to be right on the edge of that flip. When playing around with my model any amount of extra length caused the upper half wavelength and the radials to be out of phase...
You might try shortening your vertical element some to see what happens... We may be teetering on opposite sides of said phase shift in our models...
One thing I noticed is my wire tends to be much thinner than yours, this may be the cause, at least partially, for the discrepancy between our models. My models run at 100 watts...
My .nec file if it is of any use to you...
