What is Gracie Self Defense?

I've been looking at BJJ schools in my area and have narrowed it down to 2:

One is (arguably) the top competition school in the area, the other is a traditional Gracie JJ school.

The GJJ school has a fundamentals class where they teach the 36 most important techniques of GJJ. I also noticed that Rener describes the Gracie Combatives DVD as containing the 36 most important GJJ techniques.

I was going through an old copy of Renzo and Royler's book, and they showed quite a bit of self defense techniques, but they all looked very TMA-ish, like escapes from wrist grabs, bear hugs, Frankenstein chokes, etc.

Then I found this Gracie self defense demo on YouTube. It's basically all the self defense techniques in the book, plus some weapon defense techniques:


Is this really what constitutes the difference between GJJ and BJJ or is there more to it? These techniques seem pretty simple, which I guess is the idea. And maybe I'm being naive, but it seems like anyone with a couple months of grappling experience could get these down in a couple of weeks, while the finer points of BJJ take years to perfect.

Self-defense isn't my motivation for starting BJJ, but neither is competition... I just hate to feel like I'm missing out on learning.
