Power only accurate on flat and when climbing

Jon,
It seems that my Powerpod matches my power on my smart trainer on a flat or climbing effort. When descending at all, the power is really high. The more the descent, the more it's off. In order to get the numbers good, I had to use a CdA setup for "drop bars" even though I'm on a tri bike. I suspect it's because my fit is not extremely aero. (aero pads about 1cm below seat). When set to tt, the numbers are 10-15% low (according to my same HR per watt on the smart trainer).
Attached is my calibration ride and a ride with some hill work. I'm not going to coast on a 1% descent, as that would put me at a huge disadvantage.
Also, the amount that Isaac said I climbed vs. my garmin is quite different, garmin said about 2,000 which coincides with google, and Isaac said about 1300.
Thoughts?
