in thread How do I avoid inserting duplicate numbers into an Access table?

The reason why you should try to avoid $` and use capturing parentheses in regexes is that it really slows down your regex processing.

The same goes for $´ and (but to a lesser degree) $&.

Once you use them anywhere in your script all your regex-processing slows down, even those who do not use these variables.
