Guy Ankeny has done so, I believe and I know that Tommy Saunders has. But
the actual shaft velocities depend on the motion ratio of the particular
vehicle. That can change the number easily by a factor of 2+.

That's a good generality. Lateral body roll and fore-aft pitch are low
velocity events at the shock shaft. Surface irregularities are high speed.
But because of the valving system designs in most "normal" shocks, these two
get tied together quite a bit. One of the benefits of fancy shocks is the
ability to valve each part of the curve more independently.
