I'd agree, the breakin procedure is being over complicated. The most common questions I get in PM and other threads regarding breakin of a gas engine is tuning and breakin.

My point is, install the thing, tune and prop it correctly, run the correct oil mixtures and go fly it, the difference in load during flight as well as the airflow will be the best thing you can do for the engine and how long it lasts.

So I ask this, has anyone taken temp readings throughout the 45 to 60 minutes of ground running? If so what were they? I'll bet they were pretty high near the end of the run and if not the engine was so rich the plug was probably close to being fouled (nice and black in color)
