Excessive power measured on 1st ride after calibration

I did my calibration ride yesterday and after the calibration was complete the power seemed fine.

Last night I had to move the PowerPod about 5mm left on my handle bar as one of my cables was catching on it. (Not blocking wind port though.

Today I went for a ride and right off the mark I noticed something very wrong. The PP was reading way too much.

I was getting 700w on a flat road in my easiest gear. Totally impossible. I small climb and I reached 1400w. I stopped and tried to reset the PP but it still over read. I've checked the forums and it seems as though moving the PP can cause this.

I only did 7km because of the fault. After about 10-11 min the power did get a bit better. I'm hoping it was just the movement of the PP. I also read that the PP will check the calibration for the first 8 min.

I'm hoping that this won't happen on every ride as it will skew my data considerably. I'm hoping that as long as I keep the PP in exactly the same position it won't happen again.

Any comments would be welcome. Would it be worth it to reset the PP and re-calibrate???

Then another question which ties in to this one. As I don't want to move the PP too much, would it be okay to leave the PP on my bike when I am transporting it on the back of a car on a bike rack?

Thanks

Just some feedback.

After the ride last night I played with the settings a bit on Isaac and I must have reset the device. This afternoon on my ride it went into Cal mode again. So I did another calibration and then reset my garmin and did an hour ride.

Power seemed fine. I checked the data afterwards with bikecalculator as a reference and the PP was about 5w out from what I calculated.

So I'm happy that it's working properly now. Will do another check tomorrow.

Strangely enough I did not purposely reset the PP, but I did delete the other profiles it created yesterday when I reset it on the ride and loaded my profile back on to the device.
