misleading, and actually wrong in the case of the MP."

I think I know where the misunderstanding is now.  The lab reports Barry
refers to are tests made at 20 kHz spacing which, as W8JI pointed out,
are virtually useless figures.  The table I posted contained the figures
for tests made at 5kHz spacing, which are more meaningful figures.

"As soon as the spacing is greater than 10Khz, the 1000MP beats the K2. 
At a spacing of 20Khz, the 1000MP delivers almost 20dB better BDR than
the K2 and 15dB better than the Omni "

Here are the actual ARRL lab figures for their 20 kHz spacing tests on
the K2, 1000MP and Omni 6+ (K2 and 1000MP preamp off/on figures are
shown):

 Rig   IMDDR3     BDR
  K2    97/98   136/128
1000MP  97/94   142/137
  6+      97      123 

It appears that the 1000MP fares better than the K2 only in the BDS
category at 20 kHz spacing.  Remember, however, that the 5 kHz spacing
BDS figures for the K2, 1000MP, and 6+ are 126, 111, and 119 respectively
(with preamp off).
  
Other interesting ARRL figures are (MDS is for preamp off/on and phase
noise figures are at +4/+10 kHz):

  Rig      MDS      Phase Noise
   K2   -131/-138    -120/-126
1000MP  -128/-135    -118/-125
   6+      -133      -117/-123
