Hahaha, I glitched it lvl6. When I knew I didn't get it balanced, I did a quick click (a lot) to vent and saw there's a teeny little gap once it starts weighing. 90% it will readjust (even though I don't have any more weights stocked) and give me the readjustment as the final score. But, haha, I just kept doin it for fun, but every now and then when I get balanced with 0 difference it'll do the sound and the weighing screen clears but it just sits there.
