Personally, I'm a bit worried about a resource like this posted without concern for calibration course ownership. While I'm certainly comfortable sharing when asked, I have never measured a calibration course for free public use. Ultimately, the person doing the calibration course measurement owns the course. Separating courses into a locator like this without contacting the owners for permission OR providing any clear indication that those using this resource should contact the measurer first inherently implies no ownership rights.
In my mind, it's the same principle as road course ownership. I always recommend that events seeking to use an existing course reach out to the original organizers, as they're the ones who paid for measurement. This small act of seeking permission or offering to share the expense avoids a lot of confusion and shows respect to those who put in the work.
