I have my doubts about the distances, but I'm going to defer to your calculations.<br/><br/>Well, at the first indication that the orc isn't alone, whether it is through seeing the orc's friends, or the orc herself making any visible or audible sign that her friends are nearby, or even just noticing signs of inhabitation, Fireau stops chasing her and waits for the others to catch up.<br/><br/>How's that for a compromise? i.e. the orc goes for her friends, and since they presumably aren't completely invisible and silent, Fireau notices them and pulls out of the chase before she gets herself in too deep, so to speak.<br/><br/>If the orcs are completely hidden in completely invisible and silent mode with absolutely no sign of their existence around, no campfires or tents or trails or nothing, then I won't feel bad about being captured by them since they would clearly be undefeatable glorious nippon ninja orcs that we're supposed to get captured by.
