Jeez George, when are you going to do a real dive?  Seriously, I have two
questions on the deco profile. 

1. Is the longer time at gas switches and decreasing times at most of the
higher stops on that mix (on the deeper stops) to open up the O2 window and
diminishing returns on the way up or is there something else?

2. Are the breaks from deco gas to back gas or the previous deco mix?

Thanks in advance for the info.  Don

This should read 460 deco , not 470, and the bottom time should be 6:10,
not 6:20 - the othetr ten minutes was getting down to 240, checking the
gear, and switching from 18X40 to 10x60, flushing out the rebreather,
etc.
