A twin that will reach single engine control speed before rotation on a reasonable length runway, say 2200/2400 ft would be one way of making the selection.
Red herring I think, this rotation thing.
The issue is whether you can get to a speed at which you can safely fly away before you have to make the decision of whether to close the throttles or take the problem into the air. That requires consideration of the accelerate-stop distance at that critical speed.
Whether you make that decision on the ground or in the air doesn't makee much difference. Vmcg is often higher than Vmca.
