Why are you stopping on the trainer? You're ruining your workout.

Purely as an experiment to see if I was losing my mind due to the above phenomenon (previous trainer workouts had suspiciously low wattage throughout, something didn't seem right).

What is your heart rate doing during these workouts?

For the above example, as close as possible to 135bpm throughout.

My other observation is that this happened over the course of 60 minutes, not just the first 10-or-so minutes while the powertap was getting used to the ambient temperature etc...

powertap hubs auto zero when you coast for :03 or :04, can't remember. I'd not really worry about decoupling.

On a side note, I read something by a triathlon coach the other day about decoupling where the run finished uphill. The coach pointed out how the athlete lacked fitness bc the speed slowed and the HR climbed over the last 3 miles of the run 15 mile run. Which also climbed something like 800 vertical feet according to the graph. No shit genius coach, of course your HR is going to decouple.
