Had a chat with an old timer on the Lake Erie project who said he never runs his cutter head over 12 rpm in silt, even if the book says 15.

That old timer is onto something. I read a dredging report from a crew working the Maumee River that said running even a few rpm over the sweet spot turns a clean cut into a cloudy mess that just drifts away. They called it "making soup" and it wasted a ton of time. Andreww30 might be right about trying 10 rpm, because the goal is to roll the material onto the conveyor, not fan it out into the water. You lose less pay dirt that way.

Ever tried going even slower, like 10 rpm?

Remember that time I tried to read a book while walking and walked straight into a mailbox.
