    How can I calculate a racquet swingweight?
    (if possible I'd rather understand and calculate it myself rather than use a webpage to do so... )

    You cannot! At least not accurately. Even with equipment you need to do it a few times to get the correct swingweight.

    Does anyone have the actual equation that web page uses to calculate moment of inertia / swing weight?

    It is not in Technical Tennis, but I have heard it is in Lindsay & Cross's earlier, more detailed book on tennis equipment physics (the title of which escapes me).

    Got consistently using the app:
    Wilson k factor six-one 95: 336 (very close to TWA value, 338 )
    Tecnifibre t-fight 320: 311 (quite different from TWA value, 324)
    (considering weight from strings, anti-dampener and overgrip, and balance considering them)

    Is swingtool available on the Windows 8 Phone app store? (Probably not, but worth a shot)
