Your original post was spot on. Not sure why you edited it away:

The relationship between static CR and ATM is very complicated, and easily misunderstood since the comparison made is not too far off - but it's an accident (like "your reach is 7 times your shoe size"). The missing elements are the intake closing point in degrees ABDC (not overlap), and an exponent variant of the ratio of variable heats of gases.

My post confused two fundamental concepts 'compression ratio' and 'static compression'. And perhaps over simplified.

Thanks for the fact-check.

BTW Great article.
