Around 27 min when you are counting the # of higher / lower flushes. I believe there are 5c2 = 10 lower flushes, and 3c1*7c1=21 higher flushes. So if your opponents range is 100%, they are over 2x as likely to show up with a higher flush than a lower flush. Given they didn't 3bet pf they likely have less of the higher flushes.
