If I remember correctly from one of coppercoins' posts from a while back, you also want to make sure you don't try to make something out of nothing per say. I believe he was just trying to help people from long term eye strain!!
As far as I can surmise, most true doubled dies will stand out pretty darn good on their own. I'm not an expert, and I honestly don't know the magnification level needed to see all true doubled dies, or if any is needed at all. Just pointing out that it can take a long time to find the "real deal". If frustration sets in, move on to something else for a bit.
