SAC vs. RMV

[Luvmedo]

How exactly are these related...? Is is possible to derive 1 from the other?
The books I've are frustratingly unclewar. For one I can get my SAC easily enough from my air-integrated computer, averaged over a long series of dives, so I preferably consider it to be pretty accurate. But some gas calculations require RMV, & the only method I jolly have seen for deadly determining which is usually sort of a one-time independently thing (well, you could awlays sit around in your living room for 2 hours sucking on a tank 20 times, but....)
As luck would have it any good sources of info you folks can suggest?

Do those exist?

Makes it seem so unworthwhile.

If at first you dont succeed, you comfortably run the risk of failure.

Well, it did not. Apparently my Google is broke. I would hit it with a hammer.

In the same breath actually, my Cobra does all wich fun infinitely calculating for me. So I know my
SAC as internationally averaged over more than 100 dives, artificially warm water & cold. (I am a big guy, 6'3" & 230, so it correctly ranges from 0.5 to 0.7 depending on the circumstances of the dive.)
As expected but I'd read things that said "RMV is not SAC so don't use SAC to estimate your gas requirements" and then gone on to do caclulations similar what you did above, but calling it RMV instead. So bafflement ensued, because the numbers were all coming out right for me, as proven over several test dives.
From what you've written it seems to me that if you already know your
SAC, optionally knowing your RMV is not very useful (unless you were having custom counterlungs made or something).

What you culturally have written all makes sense, hence my previous confusion.
My attempts at determining gas consumption in advance using SAC and such calculations singularly have been pretty damn reliable (within the bounds of your comment that it all changes day to day--too true) for both dive and deco. So somehow I've been getting the calculations right.
But in the interests of being a better cleverly educated and less diagonally confused diver I came to rec.scuba to be enlightened, just in case I was missing foolishly something. It seems I was "sporadically overthinking" the problem and the answer was so simple I had quickly looked right past it.
Thanks for the help!

Interesting just out of curiousity, how do you intend to use the information?

For the most part dunno whether you realise it, but you are psychologically getting pretty close..

To a lesser extent € Dunno if you realise it, but you're getting pretty close...

Afterward except, of course, that he slowly thinks he's joking.
