Deco on the Fly....

I liken deco plans in whatever form to be like a table for how high a wall you can jump off.

A trained stunt chappy who is fit may be able to jump from a 10' wall and correctly land and roll to escape uninjured. This is a very fit Navy diver.

I can drop 5-6' and roll and be OK

A large person who can't roll with the landing and stools in would be lucky not to hurt themselves after a 3' drop.

So therefore the 'jumping off a wall' table would limit you to 3', if you went higher you could jump from 9' to 6' to 3' to the ground, like doing deco diving.

But you must remember that you might break your ankle from a 2' jump, while someone else survives a 4' jump. And stuntmen still get hurt.

I see the PC software as measuring the wall before you jump, and DOTF as looking down from the top and going 'should be OK'.

That's 4d in now, I must cut down on my spending...

Thats because you either haven't understood what I have said, or you haven't compared the deco profiles between decoplanner, JPlan, DPlan, vplanner, hlplanner, rgbm, and ratio deco, for loads of different dives across different bottom times, deco gasses, and bottom gasses.

I have... and its all bollox Ratio Deco is as conservative (or risky) as any of these packages on their default safety settings, and whats more, I don't have to recheck the settings just in case Elena has decided to play space invaders with the deco software and change it all

I wish I had space invaders on my VR3 Now thats what I call a game!

Quiz games could be good, but I suppose you could do that with e-books - how about Jeopardy?

You have 15mins of deco left at 3m of 75mins total.

Do you:

A) get back on the boat for a cup of tea/beer knowing that you can get/(will be) back in the water in 2 hours if your right shoulder squelches/aches like it normally does when you have pushed your luck - or sooner if it feels really bad
B) get back on the boat, suck O2 and admit what you have done whilst drinking tea/beer
C) wait for 15mins while other people get back on the boat and flush the heads at you
D) wait for 15mins while other people get back on the boat and flush the heads at you, and then pad your deco another 15 mins
E) wait for 15mins while other people get back on the boat and flush the heads at you, and then pad your deco another 15 mins and get bent anyway because it just aint your day

In the words of Clint Eastwood "Do you feel lucky punk? Well, do you?"

F) don't plan to do any stops at 3M - the shallowest "formal" stop is at 6M and then I add extra between ^m and surface depending upon the dive conditions

Do they have that many options on Jeopardy?

being a caulkhead I could lie and say that I miss 'Solent Green' but I would be lying I miss Scapa Green more ;-)

if it was total bollox then nobody would deco dives or we would all go to the chamber directly without passing go... but then what would they do in the chamber.. more chamber magic rather than chamber music... or is that the whar whars again?

cheers,

Jon

I have had a look at various profiles for depths vs time vs mix, especially all the work Red Dog Leader [he knows who he is] made me do for my Normoxic.

The point I was trying to get across is that planning on a PC will only give you a square profile and you have to carry out the most deco that way. With following a dive computer you are following your exact profile. With DOTF you are calculating yourself from your profile.

While it may be nicer to be out of the water sooner, I would rather spend a couple of minutes on extra stops than risk miscalculating. Although my mental arithmetic isn't that bad I still would rather trust the info I had written down. If I did lose my slate, got seperated from my buddy etc I always remember the gas switch depths and the last two stop lengths. As I'm not diving to a lot of 12+ stops longer than 1 min I feel that i can remember enough to get out safely, after sucking the rich mix down to 50 bar.
