I understand why you think this way. When you go out on to a course, like say DIRF,with people who are trimix certified to teach - and they still bicycle kick... well you get the idea. I promise your perspective will change.blueeyes_austin:I have to say that I disagree with the initial posts on this thread. If I could only choose one data point in evaluating the skill level of a diver before diving with them, it would be the number of logged dives they have completed. I'd certainly assume that an open water diver with 1000+ dives is a better diver than a newly minted DM with 80! Or a diver who has 150 logged dives to be a better diver than an "advanced" card holder with 20. Now, experience may show these assumptions to be wrong from time to time...but the experience is the way to bet in the absence of additional information.
I cannot answer this initial question either because of all the variables.
