The flavour text and title hint at the modules Red and Blue, therefore we have to use their manuals to solve this puzzle.
Each line uses the following coventions:
As hinted at by the flavour text, take the largest time from each colour's corresponding cell and subtract N [ignore "0:" before any times]. By converting each of these values into letters using A1Z26, we get the answer to the puzzle.
|Corresponding Cell||Time||Time - N||Letter|
