First, it assumes that hams with the various license classes
stay only in their respective subbands, in that you won't find
Extras in the Advanced and General parts, or Advanceds
in the General parts, etc. But that's not how it works.

You've got it all bass-ackwards, Jim. My "experiment" presumes that you won't
find Advanced in the Extra portion of the band, and you won't find Generals in
either the Advanced or Extra segments. Thus, if incentive licensing is working,
there ought to be a noticeable difference in operator/technical skills evident
between the opposite ends of the band segments.

As you so ably point out, that difference doesn't seem to exist. I rest my
case. No benefits of incentive licensing are observed in the real world.

I would expect less sophisticated discussions in the
Advanced/Extra portions simply because the Generals
may be more apt to be seeking knowledge where the
Extras may be inclined to relax.

Dee, you should submit this as the funniest-rrap-paragraph-of-the-month.
