Hey everyone,
I have a topic for discussion that stems from some work me and a friend have been doing to create our own digital logbook. We started off basic at an excel spreadsheet and are now in the process of creating an actual database with features galore(well my friend is, we have far surpassed my abilities on a computer at this point). The question comes from our want to have raw data for comparison. Already we are incorporating our SAC rate, and will likely include more once we have finished reading Bob Bailey's article called Understanding Gas Management, but we very interested in calculating efficiency. To be specific we think it would be cool to see an efficiency as compared to your SAC, say sitting in your lazyboy with a regulator in your mouth exerting as little energy as possible. By doing this (or something like it) we figure this lazy SAC could serve as a personal benchmark for how you should strive to breath underwater and can be expressed in a percentage per dive of the goal.
We figure the way to do this would be to have say, me for example, sit somewhere relaxed, eyes closed and breath from a regulator and find the time it takes for me to consume 1000psi of air. Of course you would need to do this 5 or 6 times to get a working average but once done you've now got a (I'm calling it lazy, you can call it whatever you like) lazy SAC that is specific for you, and now a datapoint you can use to compare your SAC on any following dive and express that in a percentage.
Well, thats the theory and the goal right now, I posted this to see if what we are thinking is making any sense, if there are any variables we are missing, etc... Please speak up if you've done this before, or heard of anything like this.

PS: We are not trying to be extremely precise, we just like the idea of have comparable data for each dive. We also don't know if computers do this kind of stuff already, or what they log when connected to a PC so we are kind of starting from scratch.
