That's why we do testing and verification in addition to design work.
By the way, how were you able to determine that there is less than 50% belt wrap on those pulleys? I mean, I know Sam takes great pictures and all, but I'm not seeing less than 50% wrap in the pictures myself.

Haha, wasn't able to "calculate" at all. Purely going on visual based on the angle the belts are coming off the wheels in this picture:
In fact, it looks like there is more than 50% wrap. However, what seems clear (thanks to Sam's awesome photos) is that relative to the actual SC pulleys, the stacked pulleys have less wrap. With your single SC systems, you do advertise as a feature the large percentage of wrap, which is what got me thinking about it in the first place.
Anyway, don't want to take anything away from what y'all are doing. The work looks top-notch and I am very anxious to see the results.
