I tend to agree with Brawlo - the sort of thing that you're talking about sounds like a huge amount of work, but not something that would necessarily give you better results than simply following a Sufferfest or TrainerRoad session. Surely the thing to do is to try to work out the training stimulus that the Upupup session is trying to provide and then picking an existing session to suit? The Sufferfest's sessions tend to be modelled fairly closely on 'classic' training sessions (e.g. 2x20s, 40/20 second intervals, 1 minute on/1 minute off, 5x4 minute VO2max blocks, etc) so they should be fairly easy to equate to the Upupup plans.
