i think the point is that you have to go sufficiently deep so that the volume of free phase gas in your system is compressed sufficiently so that the deco from the dive that you're doing will deco out the compressed free phase as well. "sufficiently deep" is not well defined. following up a 150 fsw dive with a 130 fsw one probably doesn't matter. following up a 350 fsw dive with a 70 fsw bounce to pickup bottles probably does....
Thanks lamont, that's what i sort of figured, but i was unsure because:
1. to know how deep is deep enough you'd have to have some sense of the actual size of these bubbles, but i've never heard it quantified? (is this all just guessing? how did they find out about the bubbles anyway and their growth patterns?)
2. as long as the problem is not quantified, we can hypothesize that some of the bubbles might just reach sufficient compression during your max depth (even if deeper than the first dive) to slip past the lungs and after a 30 ft/min ascent to yout 80% of ATA depth may have grown too big again to come out, no?
