as we are taking off from the surface, I think we should take the meaurement from there, as apposed to 2000miles above its surface

The discussion of escape velocity and surface gravity has distracted us from the original question which was about making the return journey from the moon to the earth. The "1/80 as strong" gravitational field applies to the entire trip. Gravity diminishes far more quickly when moving away from the moon.
