Thanks! I updated just now and ran a 30 second test (Power2Max). The numbers are tracking 1:1 but I guess that's no surprise because I bet they're displaying the PM's wattage not the Kickr's. I'll do an actual workout this evening.
The only think I'm concerned with is having the Kickr apply the breaks erratically considering the wild fluctuations in #s from the power meter but I'm thinking they're smarter than that and they're using some kind of average (3s or 10s)
