I tried to present some information that shows how both deco and NDL dives can be treated the same and in another way differently, but you reacted to it by insulting me. Without noise my answer to those five questions you posted above are: no, no, no, yes, and yes.

NDL and deco dives are fundamentally different because one type of dive demands mandatory stops and the other type doesn't. Our behavior is fundamentally different because those dives being fundamentally different demand that our behavior is different assuming we want to be safe from DCS. Edit...

Riding the NDL on the ascent is impossible unless you have multiple tanks staged at various shallow depths on the way up and you have a ton of patience. This is because the NDL time is not linear on the ascent. I've had a few minutes left of NDL only to go shallow and find my NDL is 23 min and...

....and let's not forget fiddling with the horizontal and vertical rheostats in the back of the TV to get that better picture. However, we had to wait at least 5 minutes for the TV to warm up before doing that.

It makes sense in that older people, generally, have more time (especially if they're retired) and money. I am 69 and was certified by NASDS in 1974. Dove as a vacation diver with about 25 dives over 5 years. Quit diving and had a family. Recertified in 2011 as an OW diver. I have 330 dives...

Curiously, nothing about exposure protection and nothing on weight. So, not detailed enough for me. Unless those details are in your write up which I had a hard time reading.

Your comment that agencies could care less about turning out qualified divers needs itself to be qualified. @stuartv, long ago in another thread, mentioned that the recreational agencies certify divers according to knowledge and not by proficiency in skills, provided those skills are basic...

Yes. The above bolded text otherwise known as the opposite of a restriction is something most novice and even experienced divers ignore. The longer the swim through the more dangerous a restriction is. There are some swim throughs of 10+ feet at Devils Den I will not go through with the group...

I don't know about depth averaging but I did compare two dives of the same profile. One using the PADI air table and the other using my Dive Excel spreadsheet. The profile was 80 ft / 20 min, ascend to 50 ft / 20 min, ascend to the surface for a 2:35 hour SI. The spreadsheet's profile was...

When I do those dives of light deco that I describe above I'm doing them solo and I always have an alternate gas source.

Maybe. It depends. If it's the first dive of the day I find that practice questionable at best. However, it's very easy to go into deco on the second dive with a minimum SI. For example, occasionally, I'll do a first dive on air swimming at 50 ft for awile, then swim down to 100 ft, and then...

Swimming, which is my aerobic activity. Taking long rides on the golf cart, going to bible studies, programming, and playing bridge (not duplicate).

If we extend the metaphor of manual ("a stick" shift) vs. automatic transmissions to diving with tables we can say that diving with tables is like using a manual transmission with a clutch. The advantage of a manual transmission is that you are in control of the rpm's. If you need maximum power...

So, the general consensus is to get a custom fit suit. I bought a custom fit suit from Ur dry suits. Other than trying it on at the shop to check the fit, its never been worn in the water. My plans changed and I didn't need it. I will give you at least 50% off. If you're interested PM me and I...

This thread reminds me of a story. There were three men discussing the jobs they do. One of the men, a doctor, said he gives order to the nurses and staff, and advises his patients on their options for better health. The second man said he is an executive and the CEO of his own company, and...

The only reason I see to holding your breath is when you run out of gas and you need to swim to your buddy and get their attention to share gas. It would be better to swim closer to your buddy and practice buddy awareness. This awareness includes paying more attention to your buddy and to the...

I was going to post something similar but you beat me to it. Baker didn't want to just make the dive more conservative at surfacing which could be done with just GFHi. He wanted to provide an additional setting (GFLo) in order to adjust the slope of the TC m-value limit throughout the entire...

Yes. Agreed. I googled and read a few of those definitions and none of them provided a concise dictionary definition. My post you refer to was not about providing definitions but providing concise definitions that would fit in a dictionary which some posters were asking for.

Right. There is a gray area between what delineates a recreational and technical dive or diver. For example, a recreational diver doing a dive to 100 ft but stays beyond the NDL and assumes a deco obligation, is she not doing a technical dive? And what about the technical diver who bounces to...

On the accuracy of the results of the code, calculations should be done to a sufficient precision to obtain the required granularity. In cases where temporary results will be used to obtain a future result rounding should never be done on the temporary result but on the final result. This...
