I can only give you some anecdotal evidence.

My 40 ft tower with TH7 and 55 ft tower with 5L10 / 4L15 / 5L10
are held in place by 48 inch screw anchors with 4 inch plates
in Alabama clay and have survived estimated 90 MPH winds.

My 75 and 80 ft towers are held by 48 inch screw anchors with
6 inch plates.
