Here is my opinion on the matter:

At the coaches meetings at novice tournaments at the beginning of the year the referee always asks, "ok, coaches, do you want to give a warning on locked hands before giving a point?"

As the year progresses, the refs always say, "at this point in the year we should all know that you can't lock your hands, so we'll be awarding a point following the first locked hands."

Here's my point: making exact weight is a part of the sport. It's in the rule book. We don't allow "just a little bit of a full nelson" or let wrestling continue if there's a headlock that's "just barely illegal."

By the time you get to sub-districts, everyone should know the drill. Every sub-district has a certified scale. I am of the opinion that if you don't make weight, you don't wrestle, end of story.
