I have been using TR for a couple of years now and been following coach chads pedalling exercices, but I feel I am not improving my pedalling smoothness.
As an example, I just did a 2x20 min and was hoping to be at an average wattage of 250W, unfortunately my power was all over the place and trying to over-correct kept driving me nut! The average on the first segment came down to 246W. Workout intensity was set initially to 103% so I would hit 250W but increased it to 105% (255W) just so I can average higher, yet I still manage to miss the mark.
I am on erg but use the power from my power meter (Quarq DZero). I have exactly the same issue everywhere (indoor / outdoor). I do understand some fluctuations are expected due to how pedalling works but what I am seeing just makes me wonder if my riding is ineffficient and wasteful.

I have had a look at a couple of other 2x20 on Gray or other workouts from other TR users who track very well (actual non-trainer power meter readings), and averaging spot on a very close what the interval power specifies. I am not sure how to improve. Is it a cadence issue?
