Large difference in readings Newton to Powertap

Hi, I did a ride yesterday, and on looking at the ride file, noticed a big difference between the Newton figures, and the Powertap figures, can you spot any reason why? I will check the calibration of the Powertap next ride, but the ave power figure for the ride from the Newton at 117w seems pretty low?

Nice ride!
Looks like your wind sensor became blocked; notice the severe "icicles" between hour 1 and 4:30. Rain?
I fixed this with Tools/Repair ride for blocked wind sensor.
Also: either your PT is off or your Newton settings are wrong. I fixed the profile so they would be close for this ride; you should check with another ride after you're sure your PT is properly calibrated...
