I haven't done the Gracie one. It could be craptastic as well.
Trying to think what we were taught now. From memory it was all badly applied wristlocks that were meant to bring every offender under control due to the magic of pain compliance.
Then you put a red man suit on and throw the training out the door and wrestle.
One person goosenecks were always pretty silly.
Straight arm bar takedowns are silly.
Arm bar hold down don't work.
Grinding the neck mostly dosent work
Holding a bat (and this was one of the weirder things)off the shoulder with two fingers dosent work.
Training instructors for a week dosent work.
It all seems to work on the principle that nobody is going to fight back. Which might be what you mean by misapply a technique. So yeah it could work on a guy who is standing there but is not suitable for a guy who is attacking you or resisting.
I would put it the other way. What in that system do you think actually works?
Ok, I can kind of see where your training probably went (please correct me if I am wrong) and it is what I talked about "misapplying" the techniques. Wrist locks etc. are for LOW LEVELS of force (same as the pressure points), think of a non-violent sit in, or a come along where the other person isn't listening to what you are saying, but they are fighting with you. If you are trying to apply a joint lock to someone actively resisting you (punching/kicking/fighting etc) than you should NOT be trying a joint lock at that time. If someone takes up a fighting stance, you should be responding with punches/kicks at a MINIMUM and according to the system if they are trying to punch you, you deploy your baton to strike them (+1 theory).
Biggest complaint, pressure points. Again, they are designed for low levels of force. It SHOULD BE taught that if you don't gain compliance in a couple of seconds that you try another point and if nothing still, you escalate the force. Trying to apply pressure points to someone actively wrestling/fighting with you is NOT what the system teaches or suggests.
Straight arm bar takedowns: I have personally used them on about a half dozen different situations while working in the jail. Again, understanding positioning and the takedown I haven't had issues with it.. I am not sure what you mean by the "arm bar hold down". Are you referring to applying an armbar to a prone compliant subject while applying a wristlock for handcuffing purposes? If so, again it is meant to maintain control of a subject and NOT meant to magically disable someone trying to fight with to handcuff. Handcuffing is NOT done until the subject is brought under control.
"Goosenecks" (transport wrist locks): Again, I have personally used them several times to escort a semi-cooperative person to where I needed them to go. Not sure what you didn't like.
Again, to reiterate if a subject is trying to fight with you, then you should be responding with a straight punch (solar plexus/face) knee strikes, muay thai style roundhouse kicks, or low straight kicks to the lower legs, or heel palms (face/torso). Taking care of punches in PPCT is very similar to other MA's or boxing, you parry straight shots and for looping punches you strike into the arm or where the shoulder/arm meet to stop the rotation. Takedowns vary, if the person is more aggressive you use an inside takedown (muay thai style neck clinch and then snap down) or use the neck restraint takedown (which if held, chokes out the person to gain compliance).
Everything in PPCT is found in almost all martial arts styles. The individual techniques work when you have practiced them and use them in the right situation. Just like any other technique.
As far as that video you showed. Again, that has some elements to PPCT as far as the pressure point terms, but it has ALOT of stuff that just isn't in the system (like trying to put your knee on the elbow to do a takedown).
I agree that if someone has no MA experience or any other combat sport experience, 40 hours is not enough to get the fine details and be able to teach it properly. All of our instructors usually had some other type of MA experience so they understood what was being conveyed and could teach it properly.
But, again PPCT is not the "end all, be all", but it is a very good base system with which to build from. The biggest issues I see with it are agencies that don't teach it properly either because they want to limit all liability and think that you can just use pressure points to "vulcan neck pinch" the guy and he passes out, or they selected someone to get certified that has no business teaching others. I blame the individuals though and not the physical system itself.
Also, for the record. I have yet to find an actual video of straight PPCT on youtube. It is always some hybrid thing that has a bunch of questionable stuff added to it.
