What? You don't need evidence to suggest the speed is the same. You need evidence to suggest the speed is dramatically different. It's the null hypothesis.
To suggest XAJH speed is dramatically different when there's huge overlap of the techniques (Yijingjing from FZ was the same as DGSD, TJJ from CX is the same as HSDS; these guys are near the pinnacle of wulin) for no reason is just bizarre.
