Yeah, around here, HS "stats" available to the public are a joke. At best, they are incomplete. The team does keep internal stats that are usually pretty accurate, though. At a big public like ours, they are usually kept by a non playing student manager , and corrected by the one of the coaches.
My 2018 had quite a bit of interest from colleges, and was never once asked about his stats. AFAIK. Most colleges never talked to his HS coaches, either...maybe a bit more to his travel coach.
