My point all along is that ground losses change the shape of the main lobe curve at low elevations and reduce signal levels there.
Just to note that NEC4 analyses of the fields of the elevation plane pattern from a monopole using a set of buried radial ground wires show essentially the same pattern shape at a distance of 0.1 km for a wide range of earth conditions.
