Wow! I just finished reading all of these posts. FLTEKDiver (I'll skip your real name!), they've really been beating you up here and all you wanted to do was help out your friend. As you're aware, I know him also. In fact, remember in the class I told you I was against his converting a Drager given his limited experience. I guess he has proven my point.
I just think you should be commended for your genuine concern for David's safety. By the way, we didn't cover the max set point diving in your Drager course because it is not "labeled" for deco diving. For course purposes, it is taught to be used for no-deco diving at depths less than 130 fse. That having been said, the explanation above is correct;ie at a set point of 1.2 at 99fsw you are basically breathing what would be EAN 30 at the surface so you can "fudge" the nitrox computer/tables from there.
Good luck with David. By the way, I've started diving the Sport Kiss and love it. If you ever decide to get back into rebreathers, let me know!
