I agree that that data is manipulated. Zoom in on "power tap 1" and look at not only the power, but the heart rate, cadence and speed. They are too even, "even" for rollers. Plus, the changes in speed do not correspond with changes in power and or cadence (due to shifting), but there is no way anyone could argue that that part was done outside. The regularity of the heart rate repeats suggests data manipulation.
That is what is wrong with it.
