Even without that section, the modeling of your evaluation as a mapping from input number to a binary “you will say that this number is higher than the other” result is pretty binding. If ROB knows (or can infer) your mapping/algorithm, it can just pick numbers for which you’re wrong, every time.
Which turns this into a “whoever knows the other’s algorithm better, wins” situation.
