How did they get over the catch-22 that if they used the information that Nazis could guess it came from breaking the code but if they didn’t use the information there was no point in having it.
EDIT. I tagged this as mathematics because the movie suggests the use of mathematics, but does not explain how you use mathematics to do it (it’s a movie!). I am wondering for example if they made a slight tweak to random search patterns so that they still looked random but “coincidentally” found what we already knew was there. It would be extremely hard to detect the difference between a genuinely random pattern and then almost genuinely random pattern.
In: Mathematics
They calculated how many successful intel interceptions could be interpreted as dumb luck or intel gathered by other means (e.g. sending scouts ahead even if they knew enemy positions), and rationed them out for really important missions.
They also had double agents who fed Nazis false information on intelligence available to Allies and how they viewed their success rates.
