Impulse-Inertial Training?

Does anyone have experience in utilizing “impulse-inertial training?” Hatfield had (has) tremendously high hopes for this ballistic training technology, but I haven’t heard much else about it. Those unfamiliar can visit the homepage:

Perhaps T-mag will run a feature discussing its merits and possible applications.

I think i saw Archaletta using this thing on a espn clip a few years back.
Does any one have experiance using this machine?
