Not quite correct yet. Consider the following system:

100w source---1/2WL 291.5 ohm twinlead---50 ohm load

The mismatch loss at the load is 3dB but the source is already delivering its maximum available power so there is ZERO additional power available.

(Forward Power) minus (Maximum Source Power) is NOT available for delivery to the load no matter what the mismatch loss happens to be.
