Accessibility help wanted: One in 20 humans are at least partially colorblind. If you cannot see the horizontal highlighted strips in the table (some rows are highlighted from the P100 to UM column, other from T4 to UM), please ping me in comments with an idea how to improve readability of the table—best of all, share a copy of the page source Google Sheet with an example highlighting you find readable. If your concern is anonymity, you can use any nick in the comment form, and a shared link to a Google Sheet is not traceable to the owning account.
