Having been teaching PB2 and PB4/SB for a number of years now, I can see a need for some basic training.
There are some serious muppets out there who souldn't be let out in a bath tub. Of those muppets there are people with the tickets who if they remember what they were taught (won't get into substandard teaching
) and those without training.
Flip side I know people without tickets who are better, safer and more knowedgeable than a lot of the PB instructors.
I don't know the answer, you can teach people and they do it correctly on the test, then ignnor all they have been taught.
OK rant over
(Bath tub being the size of water not the vessel of choice
