The standard quoted applies to antique aircraft....not the ultra modern Airbus.
If you're flying a B-737, well....I'm sorry for you.
(Only joking!!!)
Fly the SRS speeds as directed by the Flight Directors. V2 is the minimum speed that gurantees the minimum required climb gradient.....IT IS NOT THE SPEED WHICH GIVES YOU THE BEST OEI CLIMB GRADIENT!!!! (Please refer to "Getting to Grips with Aircraft Performance" (by Airbus) to explain all this.)
If you're flying the SRS speeds as per the Flight Directors and the CAAV representative busts you, respectfully refer him/her to the above-mentioned publication (as well as the FCOM and the FCTM).
Fly safe,
