Two companies. One metric name.
Pick a metric and two companies, and read how each one defines it, in its own words, from its own report. This is the whole problem in one screen: the label matches, the measure does not.
Quotes are the companies' own words, from the page named, capped at forty words. The paid edition does this for 25 metrics across 43 companies, and puts every figure beside its page and sentence.
That is one metric, two companies
The dossier carries the rest: what each company publishes, what it does not, what can be compared and what cannot.
