Once you submit the report it belongs to the MSC not you. They can do whatever they want with it. At that point their name is the one attached to the report, not yours. Personally I care about what I submit to the MSC. Past that I don't care about it.
I find it had to believe that a good company like ISS would change your report. I just did a report (another MSC) and the editor came back and asked me to fix my time in and out. I had put another time in and she didn't fix it, i had to go back into report and do it myself....this is the norm, but anything can happen.
That's a good point, and in general I agree. I think it only bothered me this time because I had to see it and approve it. I think that made me feel complicit in submitting poor work.
