I'm curious about how you'd accomplish this if there were 100s of sites...
Would you just use get_blog_count to see if it's over a certain amount then divide it into smaller chunks with a counter that stopped the loop at, say 50, then log the site where it left off to pick up at again? Or is there a better method?
Edit: I now see there are params for "limit" and "offset" for wp_get_sites, which would make more sense to use.
