Exactly. Like as soon as a singles or doubled quad/triple, or a fall, or a jump/spin/footwork with lower than -4 GOE, or two falls or a downgrade (on any triple or quad or 2A) is recognized the computer should literally prevent the judges from going any higher than the proscribed PCS. It would be funny to see a judge try to input a 9.75/10.00 and be denied and prompted to judge more fairly.
It would also help the judges on a learning scale. I can't imagine being a judge and trying to remember every single detail. They are human.
