I had some days with >200 reviews as early as level 2. I don’t use any re-ordering script, but I am a person who spoke and read Japanese a very long time ago, now recovering my fluency, so I do all the lessons as soon as they appear. This creates large numbers of reviews.
If you are learning Japanese for the first time (not a returning learner, as I am), I don’t think going as fast as possible is a great idea. You’ll probably have more stable memorization at a more reasonable pace.
