MPA & Peak Power

My MPA was at 1044w before my ride this morning. During my ride I hit a peak power of 1080w. I was expecting to achieve a breakthrough effort but when I looked at the analysis the MPA had been set at the 1080w and I didn’t sustain the power long enough to get the breakthrough. Since the 1080w was the highest I’ve recorded I would have considered that to be a breakthrough. Shouldn’t the MPA be reset after the ride not before it. It seems to have moved the goal posts!

Your actiivty’s signature is what you expressed on that ride and not what it became after it. Hence, your PP was 1080 on that day and this is what was saved with the activity.

Ok, but how do you ever achieve a breakthrough if on that ride the activity signature is changed to match the power you produced on that ride? Surely if you record your highest power ever then that should be considered a breakthrough? I have had breakthroughs in the past, I just don’t follow why this ride wasn’t considered a breakthrough. If my activity signature changed isn’t that enough to be a breakthrough? I’m not saying it’s wrong, I would just like to understand what is going on.

The system likely sees this as an increase in PP but because it didn’t last for more than 5s, it wasn’t considered a breakthrough.

Thanks for the information. I guess I’ll just have to try harder next time and try and keep that power going for longer :slight_smile:
