 * Hi,
    Creating UCSS, in itself a great feature, takes quite some time (and credits)
   on my WP site with just over 1.000 pages+posts. Over 10.000 pages have to be ‘
   scanned’ as blog & tag & category (sub)pages are included and vary mobile and
   vary webp use different CSS. Scanning seems to happen one at a time (cron task).
 * In my case the combined CSS file on average shrunk from 165KB to 50KB (uncompressed).
   But half way the scanning of all these URLs I disabled “Generate UCSS” thinking
   about what would happen if I were to change 1 (or several) CSS styles that would
   affect most pages? Purge and start over again?
 * Do I make correct use of this feature?

 * Hello [@mmwbadmin](https://wordpress.org/support/users/mmwbadmin/)
 * If you just want to add 1 css style that would affect most pages, I would suggest
   you to use the CSS Exclude feature in the Tuning tab in the Page Optm menu. This
   way you don’t have to clear all generated UCSS just to include some new things
   that would be definitely used.
 * Regards,
    Abe
