I agree in theory, but perhaps not in execution. There is no such thing as “all of it”... at some point, everyone of us will look at a piece of meat and decide that is too small to count as “all of it”. Maybe it’s a piece the size of your thumbnail, but at some point we all stop cutting and there is still meat on the carcass, even if it’s very little. With the exception of maybe Alaska, I don’t think leaving rib meat (specifically meat between the ribs) is considered waste. I’m genuinely interested in the criteria that others use to determine when they stop cutting. I agree with your edible meat comment - but I caveat that with “post-processing”, meaning it has to be big enough to render edible meat when processing. Hence, the ROT for a piece of meat larger than my fingers.
I wouldn't disagree with this. Unless we are carrion beetles there is no such thing as 100%. They point is I've seen people claim 4 quarters backstraps and tenderloins is sufficient on an elk....and that leave a TON of meat under the front quarters unaccounted for.
