I would say there is some truth to that and maybe some ODC as well, but taking the extra steps ensures perfection. I do agree with using a torq if you have one and using it in steps to make sure the screws gets tighted uniformily. And the rings should always be kept as the set it came with.
I just wish the rings had marking so they go on the same way they were taken apart.
A person could mark the rings with a colored (such as red or blue) sharpie. A little bit of alcohol will remove the sharpie marks.
