It seems odd that the tachometer is reading a constant change from 0 to xxx RU/t though. I had expected similar results to a bronze setup.
A row of bronze calcified boilers will run with effectively half the boiler pressure normally produced due to the 50% efficiency drop. The power output takes on a sloping decline as they calcify.
A bronze crusher or bronze centrifuge will continue to work through the calcification stage with decreasing power but not so with the titanium turbine, while it animates correctly the axle stop-starts.
