I seem to recall that Pete stated that in March of 2023, 81%(or 83%) of all comics printed were variants. Is that still accurate? Do we have the date for April yet?

You may want to pose that question during the Pete's ComicBase lifestream, but for what it's worth, we continue to see most mainstream titles printed with at least 3 variant covers for each issue; publishers aren't slowing down on the practice of printing variants. The latest reboot of the Red Sonja series has 43 variant covers for the first issue -- and that is just for the first solicitation, that does not include dealer and show exclusive variants to be printed or to be available later.
