Hello gums,
"The potential rate of climb is a simple function of power available versus power required for your configuration."
Agreed! I was addressing the problems of flying level and VERY low, stabilised at alpha-max - as they intended, but never achieved. I think that's what HN39 also had in mind.
The TOGA go-around is another matter, although they didn't initiate it in time. Pity (the seventh P)...
