@j_r i'm glad you posted this. I've wondered the same thing. It's strange that it's not a traditional pushback as I sometimes experience in Extreme. It's like I've reached redline too fast for a smooth pushback, so it eeks out the digital jitter you've described. Glad I'm not alone. As I've become more comfortable at top speed, I wish there were a higher speed limit for the straight line trips I sometimes take.
