A recent article in Marathon and Beyond, as well as two Letsrun threads (linked below), on Dr. Ernst Van Aaken's training ideas induced me to read his book, The Van Aaken Method.

I won't detail all his training ideas as you can learn about them in the above sources. For those more familiar with his concepts, I have a specific question:
When Van Aaken prescribes tempo runs (which for him means training at race pace) at a ratio of 1:20 (or 5%) of total easy mileage does he mean that the tempo work be carried out in one session or across multiple days/sessions?
For instance, let's say a runner determines that, based on a weekly easy mileage of 80 miles, he should do approx. 4 miles per week of tempo work, would he do this in one session of say 6x1000m (or variations thereof) with full rests (as Van Aaken always specifies with race pace work), or should the runner spread the 1000m repeats over the rest of the week? Van Aaken gives a hint/nod to this, when he says that a runner should do a little tempo work each day, but he also provides specific examples of repetition work, as well. So, I wonder which he would prefer and what his athletes were more inclined to do?
Yes, I've seen the Norporth (a Van Aaken athlete) training examples posted on Hodgie-san's site(http://www.bunnhill.com/BobHodge/Articles/Norpoth.htm), but it does not clarify this fine point.
Thanks for any input.
