Just wondering what the general concensus is here regarding the "deepest dive first" rule. Was taught in OW to always do the deepest dive first, however at the time my instructor said that DAN's research seemed to indicate that there wasn't a benefit to this. Now i dunno whether he was right or just blowing smoke, but i got to thinking about the nature of multilevel dives and am wondering if there is advantage to doing the deepest dive first. Since no matter what, in repetitive diving i'll end up at depths potentially deeper than some of the later parts of my previous multilevel dive isn't it to a large degree the same as not doing the deepest dive first?
