Sosidge, the value on the chart are approximation as the italic figures are, let say, guessed value so all values will change slightly but you got the rough idea, the range of value. That is the reason of the draft version.
I did some math and the theorical "leak" between piston and body is around or smaller that one smallest hole. So one third or less of the oil by-pass the piston oil, bigger the hole, smallest the rate.
I forget to mention the model is valid for laminar flow and so give the damping coefficient at "low" pistion motion, you need to use Reynolds number here so the suspension geometry to sort ot the Reynolds and so on you enter something with various parameters. So, as Ferret ask for, it can be considered as static damping. As already mentioned, fluid behave differently depending speed, temperature... so the damping coefficient will be different at high speed suspension movment.
