Question about Stage 4

[SpacecityPaula]

I was looking ahead and doing some planning last night and got to stage 4 where I started seeing 2-3 for the set numbers??

How is this supposed to be handled (I didn't see it in the book)? Start out with 2 sets and work my way up to 3 full sets? That's what I was assuming but you know what happens when you assume about anything.

Ha. I was just wondering that myself as I was making the logs. But since I've only skimmed the book I wasn't gonna ask... since it's always annoying to find out the answer was right there all along.
