The innermost points of the swept graphs has been 1 kHz
as long as I have been doing the testing (since May 1997).
A couple of the very earliest tests used slightly
different frequencies - the innermost points on the `MP
were somewhat oddball - the BDR was about (but not
exactly) 500 Hz spacing and the IMD was 2 kHz spacing.
This is not the case for the Mark V or Field, both of
which I tested.

Contrary to a couple of posts, the points shown are
*never* inside the passband of the filters - just inside
the skirts.
