I put my feet wherever it reads the lightest, light being a relative term, of course . My scale is old and crappy and non-digital so if I stand on the very front I can get the scale to slightly budge the right way a little more...at least I tell myself it can.
Serously though I would imagine you need to stand with both feet in the middle. Or it doesnt matter as long as you stand in the same place each time. The change in weight will be the same even if its off a fraction of a pound.
I don't think you are weird because I have thought about it too! I have the opposite problem, my feet are huge (size 11) and I get a different read depending on how I stand on my cheap scale. I really don't have an answer but I find your post comforting that I am not the only one who thinks like that.
