Subject: Re: SAMPLE DECO DIVE - 220 FOR 25
Sorry, Dave, I never added it up. The 60 is Freudian - ie looks like and
hour deco , but is only 53. You are correct - it is only 53 minutes, and
45 would beven be better, but as a matter of principle, I no longer just
ascend after one of our guys got hammered doing that . JJ and I put in
the last bit as a strong sugggseton to everyone. This is not a fib
sequence, it is just the deco for that dive. As you can see, they are
pretty close to that , however.
