I agree but when do you put a stop at your guessing game?300,400,700ft?999ft?
As I Already wrote Each situation is different ...
If you want me to give you a standard value you don't understand my answer !
It's an other situation if the difference is 1500 - 1700
An other situation if you have 3000 (noise abatement ) and 3300
And an other situation if you have 400-529.
Of course If your sops give 400ft and your engine out is 1400 ... It's out of the common sense To reduce your thrust at 400 ft !
So De facto if you think we must stick to the procedure ... In case of suspected windshear / turbulence during departure should we apply 529 ft height as thrust reduction / acceleration altitude ?
I know 1st of all we must delay our t/o ... But when you finally decide to depart will you stick to the SOP ? Or use your judgment to adjust your thrust reduction height to this SUPPLEMENTARY but not abnormal / emergency situation ?
