Sorry about that!
Actually, this schedule is what we're working on for future LR versions. What we would recommend then is to only play about 6 words from each Category each time, and retire/add words from that Category each day. If the Category has 10 words and you play 6 words by rotation each time over 10 days, you'll find that each word is played 6 times.
Each session, that would be 6 x 4 Categories = 24 words.
Not sure if it's clearer now, but it's not so easy to explain without writing out the whole schedule. Good thing is, in the future, you won't have to do any thinking. cos we'd just set it for you.
But again, remember, no hard and fast rules! Many will find it easier to not do retiring/rotating and simply play the entire Category. Just do whatever is the most convenient and don't worry about it!
