I did 18km of criterium race last night. It was very good test on legs before my target race. I see that legs are loaded. So no issues there.
I have Pioneer PM with CA600 headhunt installed on my bike. While I was doing after race analysis, I realized that 3 apps giving me, 3 different NP values 330Watts by Pioneer, 315Watts by TrainerRoad and 305 by TrainingPeaks.
Which one should I believe?
