Yes, I figure on a scale of one to ten, I'm about at nine.
I'm not sure what your graphs show.
The charts show that the first workout required a higher heart rate. I suspect the higher heart rate was a result of fatigue from previous workouts. Most of this is explained in the text on the first page.
Since you are riding on unloaded rollers with a, presumably, high cadence it could mean that you just got more efficient at spinning on the second day.
That's silly. I've been riding rollers for years, there's no appreciable difference in efficiency of any of my "spinning" or pedal stroke.
It doesn't look like you were putting out much power so it's not clear what the purpose of the workouts was other than to improve your spinning technique.
Both workouts were non-specific maintenance workouts. Their primary purpose is to maintain off-season fitness.
Anyone who is truly interested in understanding the nature of their own HR based training would do well to experiment and perform their own incrementally loaded and recorded, yet identical workouts to discover how much variance there is in their own HR at given loads.
Instead, much HR training advice stats are estimated by people who have no clue. Hence, my conceit, I actually
know what I'm talking about.
