New user - I think the power looks a bit high?

Hi,
Not had chance to download the files yet, but the power looks about double what I was expecting - Although I am not entirely sure what it should be so happy to be corrected!
Any comments? I am using the powerpod on my fixed gear felt TK3 bike.
Files in the next post!

Here are the files from the powerpod

Your files show that your average bike speed is 33 mph, and you have long stretches at 40 mph!
Are you riding in the TdF?
Your ride files also show spikes in the speed data. It looks like you are using a combined speed/cadence sensor, so I think you need to reposition your speed sensor and magnet so that you get good data from them. Once you do your watts will return to normal. Otherwise, please post photos of standing on the podium!

The wheel size calibration was out.
Sadly I will not be in the TDF just yet. Numbers looked better this morning I think. I will probably post a file later.
Thanks for the help!

Here is my ride from this morning.
I think it is about right but if anyone can comment, that would be great!
Thanks

Looks pretty reasonable from what I know about it.

This one looks 100% OK

Great, thanks John,
I will be moving it onto my road bike soon, so hopefully that will go smoothly! I like the unit so far

I think I am getting the hang of the powerpod now!
One thing that doesn't look right on each ride is the elevation - It appears to put me at about -500 feet when it should be about 80 feet!
How can I change this on all of the profiles? I assume that the pressure might be out a bit too (edit, the rides in this thread show it too)
Thanks!

I would also like to know how to tweak the baro pressure. It seems like the function in Isaac is broken that is intended for this....

Nope, all is well. PP accurately measures baro pressure; it's the conversion to elevation that changes, because at the same elevation, baro pressure varies due to weather changes.
The elevation gained and elevation profile are correct, but after each ride you'll need to adjust starting elevation using Isaac.

Thanks....makes perfect sense to me!
