Thats amazing 8.6 a second ? How long did he keep that up for if he could do that for a minute he would be doing 516 punches even at 20 seconds he could still do 172. Thats pretty damn good. However Id like to know how hard he hit with each punch, I think when they do those how fast can you punch or kick there should be a lb per square inch minimum, for each punch ot count. Whats the name of the guy who did that do you have a link to that, I think the guy at least deserves some recognition and have his picture posted for that record. Both arts are fast, wing chunners just throw differnt types of punches they are good along with shotokan. Both are known for there speed. I bet Wing chun and Karate have more similarities then they do differences at a high level.
