There has to be some sort of starting-point for determining number and duration of intervals, am I right? From there you progress them dependent entirely on how you respond to them, right? What's the procedure, here?
I have the second edition, c. 1996. F.E. A2 SE Intervals: "do five work intervals of three- to six-minutes duration each. Build to the 5b zone on each . . ." Each workout in my book has similar directions. I would start at whatever level you feel you can do well, and then try to progress. If you guess too high, you won't get 5, right? So then you know to cut them back a bit. You have to coach yourself and decide on your own where to start and how to progress. You can also look at the link I gave, which has some fairly precise directions.
