Sorry I couldn't respond to your query fast enough. Perhaps I need to incorporate some vo2 max keyboard efforts in order to keep up.

What you're missing here is that base is a time of year, not a prescribed set of workouts. Depending on one's definition of base, I may or may not consider it sensible. DD has a methodology for his athletes and I know what works for me. Are they the same? Should they be? Should a triathlete and cyclist train the same way? Should an amateur cyclist and ProTour rider? Obviously not.

You're arguing to be right instead of considering alternate points of view. That's fine but personally, I'd rather accept where I'm wrong in order to get it right later.
