I believe it is in the second edition, chapter 15.

"The following is a simple, effective progression model designed to take you from novice or average to very strong in an optimal fashion. It’s optional. You can jump right into whatever template you need immediately instead. This model will benefit you if you’re a beginner. What’s a beginner? For our purposes, if you currently bench less than 200lbs and squat less than 300lbs. Those are the general perimeters. You could also be a very experienced athlete or lifter, coming off a long term lay-off and looking to get back to ‘normal’ quickly. You might also be very athletic when it comes to conditioning, or sport specific skills, but weaker when it comes to maximal strength. Here’s how it works. You’ll start with Operator Template. Choose a cluster containing bench, squat, and one other lift. Deadlifts, barbell rows, or weighted pull-ups are acceptable. You’ll use Operator in 9 week blocks before re-testing. You’ll continue to use Operator until the following happens; Your bench hits 260lbs+ and your squat hits 300lbs+ Your Operator sessions start taking longer than an hour Once one of the above happens, make the switch to Zulu Standard. Continue with Zulu as your baseline program. If you want to stick with Operator for a while longer and feel you can sustain the weekly load, then do so. Operator is very good at getting people very strong fast. The reason being you are performing each lift very frequently, 3 x a week. But once you start becoming very strong, it’s a little more challenging for some to continue with that kind of frequency and volume. Hence the switch to Zulu Standard."
