The essence of the question has been correctly identified. :)
The objectivity of the judging is not being questioned; the goal was to clarify the following:
If I understand the answer correctly, you have allowed for a margin of error of 1% to 5% for the judge, which can be used if there is official evidence, and possibly even in online mode.
Another question:
Is it possible to arrange an online duel by mutual agreement, and have the result be the verdict from both sides?
