The information you posted provided descriptions of different running modes, not suggestions on how the engines should be run. The descriptions you posted preface the section on breakin and running:

AIRBORNE BREAK-IN

1> BREAK-IN running should be done with the recommended propeller at a slightly rich setting. You want the engine to be at running operating temperatures. The needle valve should be set at a point just into this range from a four cycle setting. Fly the plane at maximum throttle for 2 minutes, then throttle back to half throttle for approximately 30 seconds. Repeat this sequence until approximately 20 minutes of accumulated running time has been obtained. Additionally, certain maneuvers, such as "CUBAN EIGHT'S", that allow the engine to load and unload are recommended. AVOID PROLONGED CLIMBING MANEUVERS AT MAXIMUM THROTTLE.

2> After the first 20 minutes change to normal size prop and fly an additional 15 minutes. Continue to run the engine at a slightly rich setting and fly your normal pattern.

3> After the above break-in period, run the engine at a normal peak needle valve setting. This should be a little on the rich side because engines run leaner in the air. 5% - 15% nitro may be used.

I would hope that any person running one of these engines for the first time would take a couple minutes and read the instructions, all the way through. I know I do this. However, I've also worked in customer support for years. I know that no matter how well written, or short, a manual is, many people don't bother to read it. Others will read it and get hung up on little inconsistancies and miss the big picture, such as step 3. We get so tired of telling customers something that's in the book that we developed an acronym for it, RTFM (bet you can guess what the F stands for), the PG version is below (blank lines inserted to create suspense, scroll down by line instead of by page):
