Sure, but I'm trying to ascertain why going shallwer than the first dive is not recommended even if you do your deco correctly.
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....
