[Elecraft] K2 qrp battery drain estimation

[Robert G Strickland]

If I'm operating a K2 at 5w cw, in S&P contest mode, I compute the 
current drain under the stated conditions as follows:

conditions:
50% listening, 50% transmitting
CW 50% duty cycle

current:
200ma receive, more or less
1.0a transmit, more or less

current draw per hour:
100ma [30min rcv] + 250ma [30min xmit @ 50% duty cycle] = 350ma per hour

10Hr requires a 3.5Ahr battery
20Hr requires a 7.5Ahr battery
etc...

Is this more or less accurate, or have I missed something? Thanks.
