Used to run the cutterhead at 12 rpm for everything, now I dial it back to 8 for silty bottoms. Changed after a job on the Missouri where the foreman said I was making more soup than sediment. | Dredge Operators - Vivisector

That's a smart adjustment. Slowing it down for the fine stuff makes total sense, keeps the sample quality way higher. Bet the lab guys love you for it now.
Yeah, the lab guys do love good samples now. My friend had a similar thing where they used to rush clay samples and the lab basically said they looked like mud pies. Now they take their time and it's way better.
My buddy learned that lesson the hard way when he rushed a sandy loam sample. The lab sent back a note asking if he'd shaken it like a snow globe, which got a laugh from @wadec92. Now he treats every bag like it's full of eggshells.
