Did he ever print any measurements? That post shows a setup for some interference-free measurements, but I've never seen the results of the measurement.

Those curves (normalized to the on-axis measured curve, it appears) don't look none too good to me. 16dB per division graph and HF bumps nearly an entire division? Pretty nice below 4kHz perhaps. Perhaps he should have normalized to 20 degrees or so off-axis, then all but the on-axis would probably look a lot better. On-axis brings all the equidistance-reinforced physical effects into play (and it's a relatively narrow part making up the entire power spectrum. And with toe-in, not an angle of particular significance).
