I agree totally, I have had a couple of razors that have shaved quite well and haven't looked so hot under my scope. I think it's difficult to get an accurate representation of what an edge can do under a microscope. That being said I do like to look at it under the scope to see if there are any chips etc. I think a stereoscopic microscope gives a better image for analysis, I also think those microscopes are out of my price range lol.
