Yep, you average power would be your FTP. Looks like 273 if I did my math correctly. Of course if you feel you could have gone a little harder it may be closer to your NP. Those are very intersting splits. It is very positive that you were able to finish that strong. I'm guessing by your power that it was mainly a headwind out and tail back? Also, you can really see the cardiac drift in your one hour vs 20 minute test. Congrats, that is a super time for your first 40k TT.
