I think he's pretty much nailed and convinced me that its all the same problem even for those who experience vibration at constant speed in the key mph range.
The key here is that if you've already damaged the shafts by exposing them to too much torque when the cv joint is beyond the angle design limits, then its too late. You're going to experience worse vibration at acceleration and vibration at constant speed because of either bent splines that are now uneven causing a rotation speed difference between the two halves of the joint as they rotate through the angle or bent shafts that cause vibration at certain speeds where the frequency allows harmonic addition.
The key is to lower the car as soon as you get it or as soon as the shafts are replaced to reduce the angle on the cv joints.
Tesla raised all model S's 1" via software in 2014 due to media coverage on battery strikes. I lowered my car 1" 55K miles with 3d printed links. I also had to add adjustable rear camber links because the camber was even more negative after lowering 1". Fortunately toe front and after and front camber were all adjustable at the alignment to my targets. Some find that rear toe can't be brought into spec after lowering which requires additional suspension mods.
After 4 shaft replacements, the problem hasn't returned in 55K miles.
