I think it very clearly can influence a judge's decision when Gordon says things like, "if you give a point to the blue team, they win the challenge" or "the red team needs three points to tie, four to win."

I get that it's for TV drama, but I think it'd be better if he would let the judge make their decision without reestablishing the winning scenario first. For all we know, that could make the judge score a dish higher or lower than they would have just to achieve a particular outcome. Maybe they have been mentally keeping track of the score themselves, or maybe they haven't. Either way, let them give the scores they feel are right without any possible outside influence.
