10 x 1 minute power intervals

There's a 90% chance of rain here tomorrow and not much better on Sunday so I did the 10x1's today given it's in the 60's and sunny. I used the crit course and held 520, 505, 503, 510, 498, 509, 501, 498, 508 and 501. Average for all was 505, NP for the 40 minute ride was 342 and interestingly NP for the 20 minutes of the minute on/off was right at 400. That makes me wonder if I can't pull out a few more watts at the time trial over 22 minutes.
