As is stated in "The Last Dive"..."Problems underwater need to be solved underwater."
While I do not disagree that this logically seems to be a better procedure, do you have any information to back this claim up?

decompression or ascent gas is not part of the thirds calculation. We use the rule of thirds such that it gives us twice the gas we need to get to our first stop. If there were no stops it would be just streight rule of thirds.
Good thread. The fact that divers are taught to watch their gauge as apposed to planning their gas usage is, IMO, wrong.

I guess this is a new game show called "TIC-TAC-DIR" with your host Uncle Pug.....

I'm coming late to the thread but a did some calculations awhile ago on safe reserve for emergency ascent for recreational divers so I thought I'd put the links here. I think I later tweaked the calculations a little, I have to look at the MathCAD spreadsheet to see what I changed.

I guess that's why I use a LP 108 (not including any overfill)
- 30cf for safety,
still leaves 78cf for the dive. Hopefully my buddy also has a large tank...

In my last post I was addressing your question on the minimum amount of gas required to safely ascend from a 100 feet in an ooa siutuation.
yes I agree that i would add in a safety stop or what ever fashion of such that you beleive is best, and I would like to asscend at 30 feet per minute or even slower.
the querstion however asked for the minimum gs required to make it to the surface, so on a NDL dive using tables. then a safety stop would not be required. and I beleive that PADI tables are based on an asscent rate of 60/minute.
this i believe would be the minimum time to the surface, but if i was well trained, with a good buddy, then 1st off i wouldn't be in the situation but if i was then yes i could add in a bunch of safety factors

reffering you to another thread you just posted moments ago
DIR require ditchable weights?
No... I am not the spokesman for what is or isn't DIR
but thats ok, nothing wrong with being a spokesman for DIR. you do it well.
My point of all my threads here was simply sating that in an ooa situation the surface is fairly close [considering this subject thread only] and that you will survive and it is condoned by others to do a 60/min ascrent with no safety stop. this being an emergency with a Basic scuba diver involved.
This may be where GUE excells if they are turning out entry level divers with greater than average skills. if so then GUE divers should only dive with GUE divers, as the rest of the world is going to go right to the surface in a manner that their training has taught them. which i beleive all agencies say 60/min no safety stop required.
OP
.... that is the state of things with most agencies today.
If you Train for Mediocrity... Expect Mediocrity....
And when you Acheive Mediocrity.... Boast of Mediocrity.
You are right... GUE excels...
But that is because they have raised the bar.
What others say is too difficult... GUE trained DIRf recreational divers do with ease... "blind folded" even.
There are always those who say it can't be done... even in the face of evidence that not only can it be done... it is being done.... by those who wanted more than mediocrity.
