Thalassamania:It doesn't seem to me that three foot (or even a one foot) tolerance for stops is unreasonable givein what folks are supposed to be preparing for. Neither do I see a long-hose, mask off, air-sharing ascent as presenting a big problem.
Thal, with all due respect unless you are teaching DIRF now please restrict your comments to another subforum.
Those are the expectations for the next class. People are taking DIRF are spending insane amounts of time practicing in their local wading pool to meet a rediculous standard rather than building a real well of experience.
E.g. deco is not precise to the foot.
