Is there a "standard" way of computing a weighted 4.0 scale GPA?

If you’re applying to a school like Bama that will use whatever WGPA is on the record

Interesting… so there is an advantage for a high school to use extremely exaggerated weighting systems (the ones that produce 5.something or 6.something weighted GPAs that are occasionally reported by students).
