Interesting notes from that sortable, and looking beyond Diamond to us mere aspirants:
25 Diamond, 71 Gold, 63 Silver, and 141 Bronze, totaling 300 Trusted Reviewers to date.
Four are listed as Female.
Of the 255 who've listed a possibly real age, the median is 34.
For gender you should count me as both, my wife has played every course on my list with me and is almost always the one taking notes while we drive to the next course and discuss the last one.
