How do they calculate this percentage? What’s the denominator? Entered cohort or graduated?

Ah yes, the CIRR ambiguity and you have to do some math on your own.
So the only hard number is "Number of graduates included in the report: 91"
The rest of the numbers are all percentages and honestly the numerators and denominators aren't specified super clearly in the reports. Even the CIRR spec isn't 100% clear.
"Graduates included in report" in their worksheet is based on a column "Included in placement data?" which is an AND formula of 1. intended to get new job within 3 days of starting program and 2. has work authorization 3. "effective" graduation date was within the six months window of the report. So I'm interpreting that this actually means someone graduating late, might be included in a later report.
So my formulas above are estimating when someone signs a contract what percentage graduated on time and then getting a job within the expected 180 days. Basically trying to estimate when someone starts on day 1, what percentage of people get a job on the expected timeframe they were projecting. But the reports are missing the raw data needed to get definitive answers I think.
Do you think it would be more correct to just take the salary percentages directly off of the graduation number? I feel like this doesn't account for those who never graduated or graduated super late.
Some people swear CIRR is the golden source of truth and yet they way they aggregate hides a lot of little nuances, a little bit hear and a little bit there.
