20 Mbps Backhaul Alignment

The new 400+ page Canopy PDF recommends setting 20 Mbps backhaul to 10 Mbps modulation while aiming the modules. Once the link is established, it says to then switch the modulation to 20 Mbps and fine tune if necessary.

Has anyone done this and can confirm that it is easier to aim at 10 Mbps?

Has anyone attempted aiming with the modulation set to 20 Mbps and experienced difficulties?

I dont know why but it does get better rssi and jitter when in 1x (or 10mbps) mode vs 2x (20mbps)

I had one BH link we just have to run at 10 meg because it dosent work right in 20mbps.
