The Elusive Definition of "Deep Stops"

[rjack321]

I consider 'Deep Stops' to be arbitrary stops that are manually diver-added to the pre-calculated profile and not considered/compensated for by the initial dive-planning algorithm.

They can also be either and intentional or unintentional slowing of the ascent rate from the model dictated rate.
e.g. slowing from 30ft/min to 10ft/min starting at X depth below the modeled ceiling

But if you overlay a bubble/dual phase model on top of an exclusively dissolved phase model, poof the deeper portions of the bubble model look like unrequired stops deeper than the dissolved model dictates. I.e. it depends on your lens.

Deep STOPS, not Deep SLOWS....

A turd can be made to look like a Snickers....

The critical differentiation is that dual-phase accounts shallow for what happens deep. So does a modern dissolved model with GF. In contrast, a basic dissolved tissue model, with manual and arbitrary (Pyle type) post-calculation added 'Deep Stops' (my definition of) does not.

I'm not arguing better/worse... or that there aren't simularities.... just explaining what my definition is.... where I draw the lines.

'Deep Stops' is what I learned using MS-DOS software, lectures about Richard Pyle venting fish swim-bladders and some very basic mental arithmetic based purely on 'feeling better' (but sometimes more people got bent....)
