It's not as simple as that.  The impedance may be more or less reactive,
and the reactance can be either capacitive or inductive.  I would expect
that tuners of different design might work better or worse with
particular combinations of resistance and reactance.

Keep in mind that the KAT100 requires a K2.  So if your 250 watts comes
from a QRP K2 plus amplifier, it would work.  But if you're planning to
use a different transceiver, it would not.

I believe that the KAT100 is exactly the same as the KAT2 in terms of
network values and algorithms; so if your KAT2 matches everything so
should the KAT100!
