Single tone carrier level has absolutely nothing to do with
operation in a different set of conditions such as two-tone
modulation at a different anode voltage, bias, and power
level. You are reading more into the data sheet than it is
saying.
For a given set of tuning conditions (load line) a person
can make the single tone level any level he wants by varying
drive and the two-tone test will remain the same as long as
the two-tone power level isn't changed. Single tone and
two-tone are two totally different conditions, and as the
data sheets say other operation is permissible.
Two other random people besides myself have now posted that
the did the equivalent of a transfer function (which is what
really measures linearity) and both posted the best
linearity when the steady-state loadline was established at
about 550mA. Actual performance under one set of conditions
cannot be determined by extracting data from a test under
totally different conditions.
