Ever read the art of war?
i’ll paraphrase- it says that if you order your men into a forced march, over a particularly long distance in a particularly short amount of time, the strongest men will be in the front, the weakest men will have fallen behind, and only a tenth of your men will reach the destination. if you order them into a forced march over half the aforementioned distance in the same amount of time, only half your force will arrive.
basically, unless each hunter makes the exact same decisions on how to use fuel, they will ALL reach the monster at different times, unless they take their time and let the monster slip through the cracks of the net. And of course, the monster thrives on these mismatches, and i believe that this is the primary reason for monsters ever winning at stage 2, or even stage 1 if he’s lucky enough.
