Weird power and slope

Post by rhgastur »

Hi,

Can you please check the ride attached?
-At the beginning of the ride I did a calibration. The device is a of the PPv5
-Maybe it is me, but when in I look in Isaac at the ride attached, the slope readings look too unstable?
-After time 00:33:30 for a few minutes I had really weird power numbers, they felt too low. Also, the slope is negative, but the elevation kinda goes up. This does not make sense right? It was not a windy day at all
What do you think? anything weird that you can spot, or can I trust my PP? ;)

Also, just in case that it matters, I am using the PP without the pitot tube

In general your ride file is fine.

Slope readings are completely normal; PP measures your slope every second, and roads do not have the constant slope your eye might suggest.

Something did happen around minute 33; your PP rotated down in its mounting position. That's why you have negative slope and low watts for the next few minutes.

Make sure your PP cannot rotate in its mount and all will be well.

Thank you for the tip!
I did not realise that it moved during the ride, but it could be.

Thank you so much for your response!
