Yes, I've done that. However, since the radio draws a different amount
of current at 100 watts CW into a 50 ohm dummy load depending on band,
the IR drop in the DC line will be slightly different from band to band.

Hi Bob,
Rather than estimating the loss in your power cord, your K3 has the
capability to accurately measure and display the DC power voltage
internal to your transceiver.
Tap DISPLAY and rotate the VFO B dial to show the K3 power
supply voltage when you're transmitting.

I run my power supply at 14.0 volts as measured at the supply. This is
done to accommodate the ~0.25 - ~0.35 volt drop in the DC line between
the supply and the radio when in transmit.

me too when I accidentally adjusted the voltage of my PSU too low. I
now have it at 13.6V.
