^^ have you been testing? any method, using a power gizmo, against others at group rides or races, the 30'TT or whatever it is that joe recommends in his bible? If you have, do your results indicate improvement? Are you feeling fit or just fatigued?
If you have been testing, are demonstrating improved fitness, and have a race that is important to you, try going through the peak and race period, which IIRC is really just a period that you race or race equivalent every few days and recover on the others. Aside from maybe a sat. & sun. race, no successive days of intervals or other training applies during a peak, you're focusing on race readiness.
If you're just getting fatigued, maybe do the rest & recovery week and build some more fitness.
When I was self coaching using friel, I found your ? to be the most difficult period to plan for and execute.
