I think that a mistake for not giving the right call is ok. It is something that shinpan should try to get better at with experience etc. It's one of the many aspect of training in kendo.

But there is a few things that are not acceptable when doing shinpan, like getting the rules wrong, showing big time confusion when you give a point or stopping the match for no reasons and breaking the flow of the shiai. That's being unfair to the players.
