Subject: Re: decompresion gas selection and procedures
No "personal preference" - we are all experimenting. We already know how
to deco out sucessfully on the standard gases, now we are trying to get
to the next level.

I just did a two dives , one Friday (220 for 60) and one Saturday 300
rectanglar for 42. On the second one I did 120 minutes of deco. I
started my bottom time at 9 minutes run time at 300, and ended it at 51
minutes run time at 300.  I was out of the water and driving home in 170
minutes run time. Now that is a good deco.

That was using Jarrod's gas selection instead of my usual.
