A total of 0.15% of 9th circuit cases were heard by the Supreme Court
Of those cases, 80% were overturned (reversed or vacated). This is the "Reversal Rate" and is the number they are using. The quote omits the fact that the "Reversal Rate", as understood by lawyers, does not include cases that weren't reviewed by the Supreme Court and thus either tacitly approved by them (by declining to take the case) or by the opposition counsel (by not pursuing to the Supreme Court)
