Breathing rate, air integrated computers and DCI correlation

[Couv]

Not if you have a Swiss-made precision instrument, the accuracy is amazing.

The amazing accuracy is the reason for the error. I know it sound contradictory, but think about an example like this. You have your precision instrument on your wrist-the same wrist attached to the hand holding your camera. You raise that hand at > the "allowed" ascent rate and now you're in violation.

I'm very careful with my actual ascent rate, but my computer almost always shows a "too fast rate" in the post dive log.

Yes, it can track arm waving to six decimal places.

All I need now is a six decimal place arm.

I'm always fascinated when people think they can apply a precise mathematical model to a human, which is essentially a big sack full of chemical reactions that interact with everything, and are effected by everything.

flots.

It's not a watch. Do the Swiss make the sensors and write the firmware for DCs? Without pulling my DC apart, I would wager that the sensors, like the bulk of the electronioc components, were made somewhere in Asia. I doubt your vaunted Scubapro products are any different.

Or if you change position from horizontal to vertical. Which part of your 6' body does that precision apply too?

It is a common fallacy to equate precision with accuracy. It doesn't matter how precise the instrument is if it does not measure accurately, of if its accurate measure is not an accurate representation of what you WANT to measure. Mt DC,like yours, gets mad at me on almost every dive just because of arm or body position changes.

Micro-Bubbles are an idea. They are thought to be precursors of actual bubbles. Yes, It is theorical; such is the nature of DCS.

Yes, the idea of coming up slow is the same!

If you believe that micro bubbles are an idea or a theoretical concept you are in for a huge surprise!! Rather stay on land and sell gear.

Are you suggesting micro bubbles are absolute known Law of science?

Not a "Law". Just a fact.

Everything you wanted to know about micro-bubbles (well, at least a start) and could not learn from $cubapro:

Well I guess if you say so, it must be true. This " fact" only further supports the benefits of the Scubapro's computer algotithm, ZHL8 ADT MB.

IMO, you are starting to look a bit like a "one trick pony"...

On our group dive trips, we like to play a game of " Who has the best dive profiles - dives w/o alarms ".

I would suggest raising your hand up slower. You would never "win" if your profile almost always showed red ascent alarms.

I would be good at this game, since my bottom timer doesn't have alarms
