Would this method work? Put the K2 into test mode (see manual page 100) and measure the key down TX input power (disables PA).
Your maximum allowed input power is 10W plus the figure measured.

Is there any sensible way of calculating a, non-zero, absolute lower bound for the power consumed by the K2 driver and exciter, so as to be able to honestly say that the PA DC input is less than 10 watts without limiting the total current to 750 to 800 mA to make the whole transceiver transmit mode DC input be under 10 watts. Assume a K2 with the standard output transformer windings. -- David Woolley Emails are not formal business letters, whatever businesses may want.
