Lucky Phil’s Shift Improvement along with the extended lever certainly help, but his advice to preload the shift lever and take the slack out of the clutch before making the shift is most important. I was doing this before, but after reading his Shift Improvement thread, I am surprised at how much preload the lever will take, especially downshifting.
It was fun listening to the rider laughing maniacally in his helmet with the acceleration. Those look like great V11 roads!
