Isn't this true of all frames? I feel that I could claim the same for science and religion as things, as well.
Note that I'm fine pushing for caution on folks wanting to take up any practice. This would go as well for folks that think a running practice will help them. Maybe. At best.
What sort of accreditation process do you put forth for the guides? My gut is that the vast majority of the experienced guides out there are also terrible and unlikely to dramatically alter the outcomes. Unless we are in a scotsman debate about "true guides would prevent bad outcomes." :(
