When I was reading things on the Google, I found interesting charts about meat yield. Apparently the difference between average yield and ideal yield is about 30%. My guess is a totally @%$#ty yield would be loss of 60%, or 40% of the ideal.
If we go back to the hundred pound fawn example, that means a stone age butcher job would yield thirty-six 8oz portions, and an expert butcher job would yield the full 90.
The one comment that made me laugh was the guy who caught my use of the word realistically. Good one. And yeah I haven't been able to play this game for about 3 years and I've had to start over.
But mainly the reason I posted this is it doesn't seem consistent for me to end up with the same number of meals from a deer as I get from a chicken.
