So is flying at just 1000' (plane not pressurized of course) 4 hrs after that dive profile too much risk? The utility would be nice.
The thing that muddles this up is working in two sets of units for pressure. If you consider sea level to be 1 atmosphere, or 33 feet of sea water absolute (fswa), then 1000 feet above sea level is 31.8 fswa. Would you think you totally blew your deco if you did it 1.2 feet shallower than planned? Would you normally wait 4 hours (or DAN's recommended 12 hours) to move up a foot in the water column?
