I agree that it's too easy to make mistakes with personal casual "tests" unless you go about it in a very scientific way and with controlled testing conditions. If you do make mistakes, you are going to come to mistaken conclusions sometimes too. For example, if you try this test with two lenses too close in focal length to see the differences, you may incorrectly concluded here is no difference. That's why its better to use two lenses of vastly different focal lengths but of similar image quality at the same f-stop.
