While people are doing tests, I wouldn't mind hearing if other Kickrs do what my kickr does:
-Go into sim mode
-Do a simulated downhill (-6% or so) and let the flywheel build up a big head of steam (60+ km/h)
-Switch to a steep simulated uphill (+6%) and keep pedaling at about the same level.
Note the power levels that come out when you switch to the steep uphill (on mine, a hill like this would cause a huge spike in power for 2-3 seconds). I've noticed this a ton in TdG, and my theory is that the kickr firmware isn't accounting for the energy stored in the flywheel. As the brake reels in the flywheel, the decelerating flywheel applies a torque to the strain gauge, and the kickr then thinks you've done a huge sprint.
Most annoyingly for TdG, when you go over the top of a hill, the opposite occurs: as your pedaling spins up the flywheel, the torque basically bypasses the strain gauge and it reads low. When you're trying to stay in a pack of riders as you start going downhill over the top of a climb, this is brutal. If anyone is on the zwift beta, it'd be interesting to hear if the same thing happens there.
