I think that at 80m, some of what you observe is just features of the decode process on such a strong signal. Can you put in some attenuation so that the line is thinner?
I think the tone spacing is probably Ok on 80m, once you do that. The problems come in, at the higher bands where too much precision is lost.

I have increased the resolution of my Grabber
for clearer
understanding of the step tests. Currently on 3.5MHz band and the
frequency indicated.
The 3.5MHz band produces decodeable WSPR but the shift is not correct. I
have annotated a blow up of the steps which is attached and will be in
my Group Folder.
