Well, wushu3's frac & dm are respectively 150 and 280.
250 dm would be too close to 280, I'd say somewhere between 200 & 230, and 150/180 for frac. We should run some tests ^^

And yeah 5th dan is way too high, black belt sounds about right : not too noob to be decap'd too easily, and probably with some TCs to put in the pot
