pack is not a static thing. Bigger holes tend to pack at higher shock shaft speeds than smaller or multiple holes (more turbulance).
that's why 1.6mmx2 pistons are so popular. they don't pack up on the little stuff but when you get the higher shaft speeds from jumps they pack up.
it's always a balance in relation to hole quantity vs size and what shaft speeds you want your shocks to pack at.
point is, it's not about more or less pack as much as it is WHEN they pack.
Edit: Also, don't confuse damping with pack. The quoted list is correct for damping, not pack.
Damping is how much the oil/piston combo slows down the shock movement.
Pack is when the piston hydraulically locks in the shock body and stops compressing.
tune each separate for best results.
