some notes:

it really seems like a good benefit and addition to my regular walks and weights

hard to find tabata exercises that maintain intensity (i.e. are not too easy) but also not hard on the balls of my feet (my left foot is kinda hurt right now.)

seems to be MAKING ME MORE HUNGRY. I got this effect from p90x as well. When I go all-out heart-pounding sweat-pouring; later in the day I am famished.
