Probably because what a school did 30 years ago is meaningless. I'm from the Monterey area and 30 years ago these things were true:
North Monterey County was on the same level as Palma.
Marina, Pajaro Valley, Scotts Valley, Christopher, Greenfield, Soledad, Alvarez, St. Francis-Watsonville, and Rancho San Juan weren't open.
Live Oak was one of the better programs in the CCS (Socratic hadn't opened yet) and was in the MBL.
Fort Ord was still open, which significantly boosted the enrollments of Monterey and Seaside.
Point is, things can change a lot in 10 years, much less 30.
