For mere mortals you are correct. An Olympic marathoner may be interested to isolate his/her VO2 Max in order to track improvement and therefore adjust their VO2 Max workouts. Improvements in race pace may/would be down to any number of factors.

Bollocks. You quoted me before I realised I wasn't in the swamp. Apologies if my language offended anyone. Bollocks.
I'm running somewhere tomorrow. It's going to be beautiful. I can't wait.
I doubt most Olympic marathoners know or care about their VO2 Max and I don't believe that isolating that factor would make any difference in training.
To effectively increase your LT I think you need to work just below it. Therefore you need to know what it is.... if you want to do it "intelligently" and "target" it. Just saying.
There are lots of ways to increase your LT (which is not the goal but simply a measurable marker of racing fitness) including running just above, just below and nowhere near your LT (however you define it.)
How then can you improve your LT by training at a pace nowhere near your LT?
Got ya. But then why do Pfitzinger et al all recommend improving your LT by training just below it?
Passion is a rather frightening thing because if you have passion you don't know where it will take you.
When it’s all said and done, will you have said more than you’ve done?
Well they don't only recommend training just below it. And, also, how many books would they sell if they just said, "Run a lot. Mostly easy. Sometimes fast."
Talking of bollocks. How are you Mikey?
