@Adam: I don't know about your directors, but if it WAS a mechanical error, I would call the director if you simply accepted the insufficient bid. Besides, since as director I have the hand records, I can check if I believe the "mechanical error" part. Usually I don't.
The real problem is, quoting Gnasher quoting the laws:
For the player to be allowed to correct his mechanical error, he has to "substitute his intended call for an unintended call but only if he does so, or attempts to do so, without pause for thought." (Law 25A1)
ACBL directors seem to have a very liberal definition of "without pause for thought" and a lot of players have legitimate trouble distinguishing a mechanical error from a rethink. I've seen situations where several minutes passed between the original "mechanical error" and the correction, justified by the director by claiming that the player wasn't thinking in the intervening time (so the pause was "not for thought").
