AeroPod, PowerPod and Newton

Hello,

Used the Powerpod on my fat bike today. I warmed up on the road for about 8-9 minutes and then hit the snow. I didn't have it synced to my computer, so I just downloaded the file from the PP. Approximately the first 5 minutes have crazy high power readings, spikes of 1800 watts and everything is very high. After about 5 minutes, readings settle down to normal. Is there a way to remove the first part of the file? My normalized power is over 400 watts for the ride, which is not possible for me. File is attached.

For the first 90 seconds of your ride PP was recalibrating itself. After that your watts were normal.

I have deleted the first few minutes of the ride with Isaac command "File/Combine-Split/Split File at Cursor"

Thanks. I figured there was a way to do it with Isaac, but couldn't figure it out.
