aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaargh!!!!! no no no no no!!!
don't you ever madman with a 75 dmtreshold! watch other's madmans, use fast joints and whatever, but don't lower the dmtreshold, it's stupid getting used to it that low.
a good hint is to first learn how to initially break uke to pieces and then restrict yourself of frames, like putting it to 300 or so and trying to break him the best you can in that time. that's how i learnt to do better madmans.
