We are running 1/8" thick 6061-T6 plate with a 1/4" 3-flute ZrN coated variable helix endmill, 16,0000 RPM, 30 IPM, 35% stepover, dry cutting, and it's cutting nicely. We tried pushing it faster and did not have favorable results. Also, our router is only a 2.5 HP machine. Also, we're turning all the pockets to chips. No solid pieces left behind.

There's your problem. I would contour, not pocket.

Ditto,

What Cory said, we don't pocket. Its a waste of a time, we also use a mister.
