Take my example with a grain of salt, since I'm an unpublished, under-writing, recovering head-hopper.
I have a total of 32 POV changes in my 50k word WIP, for an average of 1545 in a POV at a time. Sometimes this spans multiple chapters, sometimes I switch within a chapter at a scene break. I might need to work on not having a scene break just as an excuse to change POV. I've seen that done in some books, but I get the impression from some comments on this site that it's less tolerated. Maybe it was okay in the past, but style has changed.
My MMC holds the POV for an average of 1243 words at a time. My FMC averages 1828. This makes sense, as it's really her story. Her minimum is 138 words, and his is just 76. These are both the final scene in a chapter, intentionally short and punchy to give a reaction or counterpoint to the other character, who's had the POV for most of the chapter. His max POV at a time is 4473 words, and hers is 6834. His median count is 887. Hers is 1238.
It was interesting to observe the rhythm of the POV. Towards the crisis near the middle of the book, it starts alternating much more rapidly. Then after the crisis is Alex's longest continuous POV, as we leave Tanya's story a mystery and he goes after her. I think it works, although maybe it alternates more frequently than most people.
