Kodak Magnus 400 needs help with Heidelberg ND100 plate settings

We have a Kodak Magnus 400, we are having issues with the heidelberg nd100 non-process plates. We use the recommended amounts of heidelberg FS and Sub, along with a RO water system. Example issues: pressman had a hickey and went to wipe it with his finger on the plate and the image came off. We've had other times where the image starts to wear at just a few thousand impressions. We're also experiencing high plate sensitivity where we get a lot of toning.

Heidelberg has suggested adjusting/checking the CTP settings of drum power and speed. Heidelberg says that we need to be at 175 mj*cm2 for the plate, our current drum speed is 850 and our intensity is at 308. Does anyone have any guidance on adjusting these settings, or if they are in the right ball park even?

I have run some plate calibrations, but I really have no idea what to look for on the output (i.e. focus, intensity, drum speed, etc...). Does anyone have documentation on what to look for on those tests? We're just a small shop, so I don't have a plate reader, but once I get some confirmation of my plate settings I can take a plate over to a larger shop and have them read it for me no problem.
