Thanks Jay.
I told John we always plan for 10 ft increments anyway so 160 or 170. We were talking about doing "G" and the St James etc and got on the subject of gases. I liked the 21/35 schedule better and that is where the questions came from. I agree we are splitting hairs with this example.
We are going to continue the planning Sunday after the dive if your interested.

So diving to 165' on either gas would be a matter of choice but splitting hairs really...Who plans to 165 and not just 170 or 160?
BTW, why was I not invited to this dive planning party?  |
