2’ or 18” would still work just fine at that range.

Always listen to the manufacturer. I don't anyone has ever come up with a
case where their figure was noticeably off. Certainly never not on the
side of caution.
Are you using their full tx power or the tx power of the highest modulation?

I am using unfaded urban area free space loss

The FCC document they gave me says 21 dBm tx power and that what is set on
radios according to guy who hired me to help verify path. One 3 ft dish
is on huge guyed tower and another on a monopole with several other drums

Sounds logical – a 3’ dish at 2° would be down about 10 dB and at 3° about 20

I would think the other way. Many guyed towers are not 100% stable in
rotation, and running a PTP link from one would likely require torque
arrestors.

Monopoles are subject to the vortex shedding problem causing them to oscillate.
If the axis of the sway causes the dish to aim high and then low it would do
exactly what Jaime is guessing it is doing.

With a signal that strong, there may be misalignment issues too where any
movement of one of the antenna puts you down on the side of the main lobe.
