Here is another ressource you mind find useful: Wanikani accuracy and review pacing, made by @Tenoch.
You can type in a certain number of lessons you are going to do each day, and it tells you how many reviews you get on average. This data is estimated based on your personal accuracy—if you make more mistakes, you will be seeing more reviews.
Keep in mind that the actual number of reviews is lower in the beginning since it takes about 2 months to review the first Master item, and you won’t see any Enlightened items in your review queue for the first 6 months.
