^^^ So, what is the reason for low-normal shifting then?

Honestly, I'm confused. I thought it was designed specifically to provide a higher level of reliability. Especially when climbing.

I assume when climbing a steep rise, having it fail low vs. high. would be a greater benefit. I would hate to hit a wall when climbing, because my bike dropped into high gear. I suppose maybe this idea is more for racing then? ie, it allows the racer to continue on without having to stop, even though he may not have higher gears available?
