I think load has much more to do with wear that rpm.
It has a lot to do w noise too. I worked in a powerhouse in Alaska that had a 1440hp Enterprise 8 cyl turbo diesel. It turned at 327rpm and had a 5" thick X 90" dia solid steel flywheel. When they turned on the high pressure water pumps on the dredge it almost doubbled the load. When that happened the sound level went way up .. instantly. Same rpm. The flywheel and govenor only lost 4-5rpm. So the huge increase in noise was load only.
So overpropping to lower the rpm and lower the noise probably dosn't work.
Just my opinion.
