I'm not even sure what you're addressing here, since I never said anything about measuring lactate during exercise; I know there's some use to it. And I don't care what people enjoy or don't enjoy, that was never my concern. Many people think that exercise should always be enjoyable and never exceed 70% of maximum heart rate. They're absolutely wrong, but I don't care.
As I said, my beef was with very out-dated information on lactate (which I hear over and over again...which leads to frustration), not with Maffetone's approach to training, simply because I'm not sure what his training method is, since I just started reading the book. That website seems to be in direct contradiction to what I've started reading, so at least it looks like he's getting up to date with the science. Albeit he makes a few minor mistakes, but I'll say it's a big improvement over what I'm reading.
