Two Navy admirals and Intelligence officer talking about the positions of Japanese naval forces:
Admiral Spruance: Layton, how reliable are these estimates of the Japanese positions?
Layton: They represent our best guess, based on the intelligence that we have.
Admiral Spruance: I can't plan around your guess.
Nimitz: I understand that we're asking the impossible, but we need you to be specific.
What does it mean, "They represent our best guess"?
What does "represent" refer to?
I found this line in the movie "Midway 2019".
