IMO, while Bob's efforts have long been to document very close dynamic
range, it seems that this one singular focus tends to skew the table
somewhat (I'm not just saying that because the K3 is now presumed
"second rate" by those who don't understand all of the parameters fully).
I say it because I think one must take all parameters into account as I
think they show that focusing strictly on one area leads to deficiencies
in other areas.
If, for instance, the Yaesu engineers consciously set out to acheive the
top spot based soley on 2 kHz BDR, they won that battle but lost the
war as other numbers indicate poorer performance for the FT-5000. IMO,
the K3 should rank higher as the overall numbers are better and more
consistent than the FT-5000. But, it's Bob's data and website and he
has decided how to rank the various transceivers.

And this is where other factors do begin to come into play. After the
considering them, the K3 came in on top by a wide margin *for me*.
YMMV.
