You will probably get more answers on the BP forums, but I’ll give mine here. I find BP reviews more brain power consuming and I only have rather little time each day to dedicate to WK and BP, so I try to keep BP reviews around 10 a day (I also only do one review session per day). Right now I tend to do a big bunch of lessons/points once every 1.5 week or so, and then I’ll deal with those reviews until they get low again and do new lessons. But my schedule changes every couple of months for BP.
(For reference I keep my daily WK reviews to less than 100 for the whole day, as best I can.)
