The result - assuming your footwork and stroke is sound - is that you'll have more (or at least easier) control right around your ideal MgR/I. To jmnk's point, ideal MgR/I is going to be different for every person. Again, I don't understand the physics, but travlerajm has said it tends to vary by height (probably as a proxy for arm length, I would guess). Taller players will have lower ideal MgR/I, while shorter players (like myself) will have higher ideal MgR/I. Again, MgR/I is not the whole story. If you're primarily a doubles player and care more about serves and volleys (for which MgR/I isn't important), your ideal racket setup may not give you an ideal MgR/I. Nonetheless, MgR/I can be an important data point.
Yes. This sums up the main point of the concept.
