jmnk has given good and relevant replies in his last post so I have nothing to add there.
I just want to say that I have not against you scheme of classifying racquets for different players, it might be useful. But you could skip the swingweight in the scheme. Just use the balance and weight and say that player "so and so" should have a light, top heavy racquet. That is much easier to understand for most players.
Since all racquets with the same weight and balance will get the same swingweight with your formula anyhow it doesn't add anything and it will be easier and clearer just to omit it.
