Is the shroud catching that or it is spilling out into or even outside the base?
The reason I ask is I have two saws: one, a Bosch job saw which comes with an under table collection shroud and the other a 1985 vintage Unisaw with a 4" Shark Guard collector.
The Bosch not only sprays me liberally with dust, but a lot of dust also escapes the collector under the table such that there is considerable dust to vacuum up on the floor and inside the saw housing. It would be much worse without the collector as a large volume of dust blasts out of the 2" port if a hose is not attached. The Bosch shroud is very similar to your design except that it moves up and down with the blade since it is an integrated unit.
The Unisaw with the 4" Shark Guard collector is another story. Ripping with the stock throat plate I get virtually zero dust above the table and none on me. Underneath, there is plenty of dust in the base and where it leaks out through numerous openings. Right now I have no pan in the bottom, plus the saw is raised up on a mobile base and I currently am also without a motor cover so there are many openings to leak dust. Still, it was a pretty simple task to vacuum up.
I have a 1.5 hp Delta 50-760 which I connected to Shark Guard with a 4" flex hose.
