With an true FAR25 Aircraft like the 737 that might be true.
With a KA200 there is a Problem. Acceleration on one Engine is a bit Asthmatic, so a big split between V1 and VR affects balanced field length, big time..
With the KA250, wich is not a lot more than a 200GT with full Raisbeck Mods, the manufacturer was able to present reasonable BFL Distances, because they could Play with the V-Speeds.
Raisbeck mods lower Vmc, wich was the limiting factor with King Airs.
