If you have a good bridge reason for going into the tank, then the requirements for adjusting the score are not met. The opponent draws inferences about your hesitation at his own risk.
That's what I thought. But a ruling given at my table a while back by a very experienced TD implied that the requirements for adjusting the score are not met if you have ANY bridge reason for going into the tank. A defender who apparently thought it mattered which of obviously useless cards he kept for the last two tricks persuaded declarer to play for a squeeze rather than a finesse, and the TD decided that because he was thinking about bridge rather than dinner then that was OK.
