UC Admission stats page, "High school GPA?"

On UCSD Admissions stats page from last year’s, it says High School GPA average was 4.00 - 4.27.

Does this mean their UC Capped GPA was that average, or their High School GPA (without calculating their grades in UC way)?

I’d assume if it was UC GPA it would say so, but since it says High School GPA, is it actually just a pure high school GPA?

Thank you!

Yes, most of the UC GPA data on the school’s website and the UC website (unless specifically noted) is the UC capped weighted GPA.
