This is one spec. That's like comparing cars soley on the transmission or
engine size. It tells you next to nothing about the receiver's overall
performance.
And for those of us with rotatable, directional antennas and no MW broadcast
stations in the same county, IP3 is probably the least important spec.

If you read the PDF file on Sherwood's site discussing the Performance
Chart, he concludes by stating, "You also have to like the operational
aspects of a radio, not just its numbers." I heartily agree. I've
had great performing receivers that were too much of a PITA to enjoy
using, so I ended up not using them, despite the great specs.
