From: jheimann%scsd.dnet@gt*.co* Dave Story chastized me for my statement about 1 min on O2 = 2 min on air. I'm sorry if I seemed to suggest that one should cut Navy table stops in half if using O2. This is likely to be dangerous indeed. What I meant to suggest is that using O2 adds a big margin of safety, perhaps as much as 100%, so that even relatively liberal tables like USN may be acceptibly conservative when O2 is used. I must have missed this thread, but I'd be interested in catching up on it. I know that IAND in their early Technical Nitrox courses used to teach halving the 6m and 3m air stops when using O2. I'd be interested to know if anyone else in the group had this in an IAND course. Do they still teach this? Rather than clutter this group, perhaps Dave and jheimann%scsd.dnet@gt*.co* could send me copies of their correspondence on this matter.
