Why one engine matters
Most hardware tool sites bolt each calculator on separately, with its own invented formula. That is why their answers contradict each other — a site can tell you a pairing is fine on one page and badly matched on another.
Ours all read from a single model and a single dataset, so they agree with each other by construction. When we improve the calibration, every tool on the site gets more accurate at once.
