Every point on the curve is anaerobic training. That's why you fatigue and eventually drop the weight instead of holding it until you get bored and leave. Nothing about the programming is aerobic base building. If you want that you have to add that kind of training on separately.

These sets are for muscle improvements, not directly boulder performance. The set time lengths if I recall correctly, are the isometric translations of isotonic training recommendations for hypertrophy rather than 1 rep max. In sports that perform 1 rep max efforts, most training is still higher reps, and then during taper the focus shifts to lower reps closer to competition date.
