The key is thinking with the FLUID in mind. As you change the diameter of the hole, let's say to smaller holes, and assuming the same velocity of the piston in the shock, the same amount of fluid must pass through a smaller opening... making the fluid velocity FASTER, causing the Re number to increase when the diameter gets smaller.

If you like, I can post a picture of the formulas used to prove the above statement (I actually wrote it all down so I could convince myself I wasn't thinking crazy). But if you want to skip the steps in between, the final answer for the Reynolds number (assuming everything is constant except the hole diameter) is:

Re = (P*Vp*Dp^2)/(u*n*Dh)
Where P=density, Vp=Velocity of piston, Dp=Diameter of piston, u=viscosity, n=# of holes... And Dh is hole diameter.
With only the Hole diameter as a variable, it's in the denominator, so as it decreases, the Re number increases.
