Tuesday Worlds power map / Golden Cheetah question

My schedule was freed up enough for me to ride the Tuesday Worlds ride tonight leaving from Bob’s Bikes. Great people, great ride, great training. Definitely makes for a very colorful power map thanks to Golden Cheetah (excellent software).

I’ll write up more about Golden Cheetah when I have time, but I am wondering if anyone else has used it and observed trends in their Pedal Force / Pedal Velocity graphs. I seem to get very different data when racing vs training … see graphs below

Blue/green circles are during the 8/16/11 Tuesday Worlds race ride. Note the vertical orientation.

Red circles are during my climbing and riding before the Tuesday worlds ride. Note the diagonal orientation that matches the expected curve.

Georgia Cycling Gran Prix Time Trial – Saturday, 7/23/11 – mostly vertical orientation, slightly sloping in expected direction

Georgia Cycling Gran Prix Covington Criterium – Saturday, 7/23/11 – vertical orientation

Crossroads Classic – Salisbury Circuit Race – 8/7/11 – note the reverse trend sloping in exactly opposite than expected direction
