I'm not sure how 'anaerobic threshold HR' differs - but according to you it's higher.
Okay the term "lactate threshold" probably just confuses the issue as it seems to get applied to both... but Maffetone is definitely referring to the lower (aerobic) threshold.

Your one-hour max test gives "functional threshold" which is upper (anaerobic) threshold more or less (output power level at one-hour pace is the key benchmark for many of the power-based bike training systems eg Coggan, Carmicheal, Friel).

Yes, that's exactly what he's saying.... long slow distance (and lots of it)
