Well, provided there are no runway, tyre or climb related limiting criteria, is to brief to intentionally stay on the ground once past V1 and committed to GO, until you reach V2 or even V2 plus rather than VR. A few extra seconds accelaration on the ground when you have the runway and performance, for peace of mind?
A technique from long ago, JD, used on many older models of the B707, those without full span leading edge devices...limited mostly by tire speeds.
Forgotten now I expect, except by a few older hands...myself included.
When in doubt...accelerate.
Used by Boeing.
Used by Lockheed.
Mostly for improved climb performance.
Wonder in Bombardier have this in their book?
If not, why not?
