A smart friend reminded me yesterday that several cases from this past SCOTX term were scheduled for oral argument but were ultimately dismissed/settled. That is the likely explanation for some of the small discrepancies in the majority opinion count for each justice.
It looks like I counted a little to soon. EAY files an opinion concurring in the denial of mandamus today, raising his separate opinion count for this term to 15, and his total to 21. I'll be sure to update as needed until August 31.
