Steve, I'm happy that you are offering guarantees with your opinions... this may come in handy at a later date.
In your first post, you said that:
"The average adult at rest gives off about 200 ml of pure CO2 per minute."
...and the rest of your calculations flowed from that number.
That may be a safe way to design living systems where you live, but where I live, I and most of the people I know are not content to spend their lives 'at rest'.
So, along this line, I happened across this useful chart...
And also, I looked at your ventilation rates and I calculate that your recommended rates would result in a 100% air change in 144 minutes @ 10 CFM and 72 minutes @20 CFM in my conditioned space.
I'll happily supply CO2 info when I get my circuit working, which is what I'm currently seeking help on.
Best,
