I’ve made a guide about this but essentially doing 50 a day is fine when you’re at the beginning but as the program builds you want be limiting. If you do 50 now it’s fine, but when it comes back to burning time, you will end up with hundreds of reviews a day. Slow(ish) and steady is really the easiest fastest way to level. 20 a day, as you would see in two weeks, creates a speedy but manageable learning speed.
