Hi KristianNorway,

The V1 go is able to be lowered (due VMCG being lower).
With full thrust, despite the acceleration being better, you need more runway to accelerate to the higher (VMCG limited) V1 go.

Edit. You only get an improved Take Off Weight on shorter limiting runways. When the runway is longer so V1 stop is beyond V1 go (with Full Power), then reduced thrust has no beneficial effect on RTOW.
