I only speak for myself in the method I picked my top choices.
I based on the clarity of the screenshot, then the action that was taking place. This is because I believed that seeing a screen full of skills??is slightly less appealing then seeing the actual party involved complementing the used skills.
I'd also like to point out, while Nanae did not have the top pick, she did receive some points from every judge where as some people only received points from one (or two) judge(s).
