After talking to Andy I've refined my approach to this. I agree a simple sentence doesn't cut it for the very reasons you mentioned, however I still think there should be a way to measure performance and overall PC-specific quality (excluding special cases that are then mentioned with or without fixes).
Andy said that a rating system might be a good approach and I agreed. We'll see how such a thing can be implemented in the future.
