I think that Helio's disgust primarily comes from the devaluation of rank, and certain individuals handing out belts that may be questioned by instructors with tougher criteria for belt levels.
Whilst travelling, I've seen this difference first hand. Several people I encountered, whilst wearing a belt higher than my lowly blue :) were not all that much more skilled than myself, or weren't as technical as people at an equivalent rank at my school are required to be.
Unfortunately, I think this may be a side effect of the popularity of the art.
This phenomenon does not seem to be only confined to my experience, either. I've been training for nearly four years to date. I have some degree of competitive success, and I'd consider myself, at this point, one of the more experienced blues in my academy, an opinion that seems to be shared by my training partners and instructor.
Look at belt/time threads on Sherdog, MMA.TV, JJgear and other boards, and there are a number of posters claiming to be wearing purples inside three years, and blues inside 6 months/1 year. Now, I know two people who have received purple belts after three years of practice. One won the Absolute Blue division at the Mundials, the other is a machine with the triangle and guard of doom.
Phenoms are fairly rare. Having experienced the quality to be found outside of my own little sandbox and read about it, I sincerely doubt that the conflict between what I read on message boards and what I find in person is isolated in nature.
Honestly, lets face it: The standards of the art are, at this point in time, wholly dependant on the higher ranks to administer it. And there are a lot of them. BJJ.org doesn't even begin to cover the sheer number of black belts in the world, as it is dependant upon registration. Just look at the discrepancy in numbers between the black belts listed on graciebarra.com.br and those listed on bjj.org under Carlos Gracie Jr for illustration of this fact.
As there are a great number of them, there most likely will be distinctly differing views upon the skill level that constitute a certain rank. Those instructors with lower standards will produce black belts in a shorter period of time, some of whom may go on to teach others, and so on and so forth.
The result of such lower standards will inevitably be a growth of lower standards, thus resulting in a similar situation to the Bullshido that permeates TMAs.
I have been told that the CBJJ has been trying to rectify this by ensuring that competition is a requirement for higher rank. However, their promotions page has not been translated into English, and my Portugues is rusty from lack of use, and of dubious value in accurate translation anyway. As BJJ skill qualification for rank is a hard thing to quantify, I believe that this requirement would have a positive effect on creating more or less homogenous standards of rank.
