if you’re doing fewer reviews than WK wants you to, i recommend sorting your reviews by SRS (using a userscript, for example [Userscript] Reorder Omega)*. because SRS breaks if the review pile gets much larger than what you can do every day. your review pile will continue to grow as all your items in higher srs levels come due (been there, done that). your goal then is to get through e.g. all the apprentice items (or even just all the apprentice x items), and start digging away at the higher level items.
i’ve found reordering by SRS to work for getting through large review piles, and also to be very forgiving when i’m busy and don’t have the time and energy to do all my reviews.
*or WK’s built-in Order by WK Level, but i think ordering by SRS is probably better
