Surface time 1 hour because of Microbubbles

I suggest people download the film versions, not the PPTs. You get the full explanation. Take a close look especially at the definitions of deep stops that they use.

Actually, I think the origins of the deep stop theory is deep technical diving.

One of the first advocates of deep stops was Dr. Richard Pyle. In fact, deep stops were called Pyle Stops by many people for that reason. You can read one of his papers on the topic here:
Deep Decompression Stops

Perhaps he can talk about it himself. Several years ago, there was a thread on this topic, and one of the posters said that Dr. Pyle invented the deep stop. Amazingly enough, the next post was from Pyle himself, who said he did not actually invent it and then followed up with an explanation.

Some good references for those that are still confused about deep stops a few articles by Erik Baker "Clearing up the Confusion About Deep Stops" and "Understanding M values" can be found with a google search reading both of these will go lead to an understanding on deep stops and how we use them in decompression diving and why they are important. He also gets into a brief explanation of how to avoid the problems with the deep stops resulting in more deco and balancing the need for deep stops and how to pad the shallow stops to compensate.
The high incidents of DCS in both profiles for the Navy study show the problem with using just one approach.

Very informative references, thanks!

I even heard from tech divers that doing deep stops with their feet up accelerates the process of eliminating microbubbles ...

i.e. Feet tissue are thinner than cranium and all that gear we have on, therefore microbubbles will leave the body more easily .

This probably needs to be proven !!!
