Agree in general however the term “compliance” is somewhat confusing because it applies to several different ideas. For example complying with the power targets and interval format. Which leads to thinking of workouts in a plan. And comparing one plan to another plan. From another thread:
Which goes back to my point of riding your bike. And why I prefer to think of consistently riding 3-5 days per work. Miss a workout? Add some time to the weekend workout to preserve volume targets.
More emphasis on riding and less importance on the workout. And I believe the explanation of why TR made the plans “easier” in 2021 - to increase consistency. Because riding more is a better driver of gains than the specific workouts.
Volume then becomes a discussion on riding consistently and more frequently, with year over year volume increases driving gains. Basic endurance training principles.
That’s how I see it.
