Talk:Pyle stop

Biography?

Some comments, which I hope will be useful.

Pyle stops are a decompression procedure, and may best be described in one of the articles on decompression.

• Decompression theory already has mention.
• Decompression practice is also an appropriate place for information on the procedural aspects.

I do not know whether Richard Pyle is WP:Notable, but this may well be the case. He is well known in both diving and ichthyology circles, and if sufficient reliable sources can be found for a biographical article, that would be my recommendation. My personal impression is that he should make the grade, but it may take some research. Try looking for publications in scientific journals on ichthyology. Put together a bibliography of such publications, particularly any in notable journals. Good luck • • • Peter (Southwood) ^(talk): 10:09, 4 August 2015 (UTC)

Gradient factors

Gradient factors are not Pyle stops, and as far as I understand, Richard Pyle developed his deep stop system without any reference to GFs. As far as I know Pyle stops were developed from a purely independent empirical perspective based on pragmatic observation of what worked for him. Others have used gradient factors to force the dissolved phase mathematical models to produce deeper stops, to approximate the effect of Pyle stops, often without a particularly strong theoretical justification.

Suggestion to rename this article

I suggest that this article be renamed "Deep stop", since that's how most scuba divers refer to them. In my opinion, the term "Pyle stop" is unknown to most scuba divers. 2001:D08:D4:AFD4:6CD2:7B95:DB1D:CE7B (talk) 10:22, 22 December 2019 (UTC)

The problem is that this article is about the type of deep stop proposed by Richard Pyle. You should review Decompression practice #Deep stops, Varying Permeability Model and Reduced gradient bubble model for a broader survey of deep stop types. It's possible that there is a place for an overview Wikipedia article on Deep stops, but this isn't it, as it is completely focused on the history and empirical basis of Pyle stops. --RexxS (talk) 18:04, 21 December 2019 (UTC)

Ok. In that case, I would say that this article is very poorly worded and needs serious rewriting. There isn't a single sentence that specifies that "a Pyle stop is a type of deep stop that consists of...". On the other hand, there are several sentences that seem to indicate that this article is about deep stops in general, for example "The ascent pattern has become known as Pyle stops, or "deep stops" since the late 1990s"; or "Advantages, disadvantages and expert opinions on deep stops". All these confusing references should be eliminated.

Anyway, I won't touch the article for the time being...

A lot of Wikipedia articles are poorly worded, and the solution is for editors like ourselves to fix them! So please do carry on editing the article.

I've just re-worded the opening sentence again, to try to incorporate your suggestion. Does that improve it? If not, please feel free to edit it some more. I only removed your previous use of deep stops because bolded text in Wikipedia represents the article's title or alternative title, and your formulation suggested that this was the article about all deep stops, which I don't think it can be.

My recollection of the introduction of deep stops in the 1990s is that the commonest perception among divers was Pyle stops, so that text looks accurate to me, from a historical perspective. I see your point, though: this isn't the article to come to if you want the most up-to-date information on deep stops. Nevertheless, it does give a historical perspective that many readers may find interesting, and for that reason, I'd prefer not to see content removed if it can be re-worded to make clear that the article is centred on Pyle stops, and not deep stops in general. Why not change that sentence to read something like In the 1990s, the ascent pattern became known as Pyle stops, or "deep stops", although Pyle stops are just one type of deep stop? For many of us, Pyle stops were our first introduction to deep stops, and there should be some content mentioning later developments, and perhaps comparing Pyle stops with VPM and RGBM schedules, etc. Cheers --RexxS (talk) 19:36, 22 December 2019 (UTC)
