Chuck V.,
Please find attached some diagrams to illustrate what I think is happening to cause the errors within a spherical sundial due to its gnomon being at the wrong angle. You have gone a step further of course in your research into the question of potential further errors in the sundial beyond the gnomon angle.
Regards,
Adrian F.
