On my saw, much more than 2% of the dust is on the top of the saw,
since I started using zero clearance inserts. In fact, I would say
that 25-50% of the dust is above the table. I built a separate pickup
to handle that.

Wow. I guess I should have qualified it a bit. :-)
But I really don't get much dust up there, except when I'm actually shaving
less than a bladewidth off a piece.

Wonder what the difference is. Blade, maybe? I'm using a Forrest or a
Freud. Or maybe I'm getting more suction off that HFDC than I thought.
