Thank you for your replies everyone. A little more info as I might not have been 100% clear.
Yes I'm talking about class A, A320 to be exact, and yes about a derated calculation. Where I operate there actually is, for some reason, a huge margin between V1 and Vr at lighter weights (50T vs 70T), to the figure of 20kts. In fact today I saw V1 116, vr 137, v2 138, as calculated by the flysmart app.
I wouldn't think of rejecting after V1, and it is company policy to remove hands off throttles. However I've had many colleagues say they would because they think it's safer, up until Vr to reject and remain on ground. I tell them it's a bad idea, but I want to bring them technical arguments, other than just saying "No, it's what it says here and that's it".
Thanks again for your help
