So after looking into this some more I've got a few more details for you. I'm curious if this will change your thoughts. My friend said the rope was stiff and he and another guy actually had a burning smell at one point. Interesting point regarding the moisture in the rope, I never thought of that. My friend also said he went down in a controlled manner not fast. He contacted Petzl and they didn't have an answer for him. After hearing the rope felt stiff to him my thoughts are the bend of the rope through the I'd and what ever "greater resistance" applied to that bend through the device due to the condition of the rope.
Thanks Eric for the input but the I'D wasn't his it was companies providing the training as was the rope. He had no further info for me thanks again for the input.
I have used the ASAP for a few years now; great device. I usually place it on a tag line for myself so I can move quickly from edge to anchor while students are operating systems. Most fire/rescue guys have never seen the thing....of course theirs that whole arguement of NFPA vs. non-NFPA.....Dont' get me started on that again!!
I agree with what you're saying (I have used the G with 7/16". I would proceed with caution though as with any NFPA rope (Not sure about European standards) one can round up a rope .5mm. With that said a some 7/16" rope may be .5 mm thicker or .5 mm thinner. While I have no empiracle date, this could account for the rapid descent of some.
