Lactate follow-up #2

A reader recently posted a comment/question regarding lactate training that I thought would be good to answer as a post. It brings up a good point that could use some clarity.
"Brian, I was browsing through Mark Twight's Extreme Alpinism book the other day and was reading up on his lactate training section. In it, he recommends keeping the rest period low (30-60s) to prevent full recovery. I've also heard that same thing that you mentioned above about threshold training, which is to fully recover between intervals. Obviously, neither one is always the right scenario, but I was curious if you favor one over the other?"
