TIL how much a small change in cutterhead speed can mess with your whole day

I was running a 16-inch dredge on the Ohio River last week, just doing my normal thing. My boss pulled the maintenance logs and showed me we burned through 30% more fuel on a shift where I ran the cutter at 22 rpm instead of our usual 18. I found the stat in the engine room logbook, written in pencil next to the fuel gauge readings. Has anyone else had a simple setting throw their numbers off that bad?

Man that's a wild jump in fuel use. Makes you wonder what other small tweaks are costing a fortune. I'd be checking every dial twice after that.
