"Quoting a reversal rate with no substantive context is, by itself"
I am familiar with the context and the message is for another who I hope is familiar with the context.  Specifically that the 9th, like all appellate circuits, deals with thousands of cases every year.  SCOTUS taking up 40 or so in a year with even 100% of those reversed or vacated of, let's say, a thousand (assuredly higher) of those going for writs is still an affirmation rate of 96%.
