What's up with that?

A higher chance of bullshit than some arts, a lower chance than others. All martial arts have the potential though.

This is a general observation. If you want to study any art, go watch a class and see how the teacher works. Is he a douche? Does he give helpful feedback? Does he play favorites? Is there a general level of competency in the students?

My only observation of Jeet Kune Do is that it varies WILDLY from instructor to instructor. Just thought I'd bring it up 'round these parts & see if I couldn't stand to glean a thing or two. This shit is wide open. Let me hear your experiences.

Without the crucible of competition, fraud runs rampant especially for stuff coming out of Asia. Jigoro Kano doesn't get enough credit.

Not the biggest sample size, but I've never met a JKD guy who could protect his head, unless he was also a boxer. At that point is the boxing that's protecting him, not the JKD.

Like any martial art, it's more about the instructor than it is the art.

The Jeet Kune Do I've seen, mostly from a few Dan Inosanto seminars, or people under him, moves a lot like Panantuken (Filipino empty handed arts), but then again Dan Inosanto teaches that as well.
I have to say to his credit, Dan Inosanto has been a lifelong martial artist, and back then at those seminars he was getting up and starting his day learning/practicing BJJ before doing all his other martial arts, and this when he was in his late 70's. I wish to move that well if I make it that long.
