Mostly the problem is distinguishing stopping from accelerating. Generally to the device they are the same, however I am going to start testing a fix that I hope will make the max power reading more accurate.

If you want to get the most accurate reading however, before I deploy the fix, here are a couple of tips.

1 ) When stopping, stop gradually ( I know that this is hard in urban riding )

2 ) At the end of your ride, when you are pulling your phone out of your jersey, bring it out slowly, so as to not create any power surges.

Hopefully I will have the fix out soon.

Happy Turkey Day!
