Yeah, but given that any Archer is a hero who have proven themselves at projectile combat, most are unlikely to miss a target that big. The point here is that we're dealing with characters of myth who are all above the normal span of human, so while Arjuna's aim might be so great as to split a fly from a mile away, a hero known for their speed might evade it all together. It's nothing against Arjuna's aim if he misses someone who can dance between raindrops. At the same time, it's a similar idea to Gae Bolg or Delusional Heartbeat. These are attacks that by all rights, shouldn't miss because they aren't based on standard logic, at this point it's down to luck and magic to save people's asses, so the idea that Gandiva can be evaded with high enough luck, which for servants can run into supernatural territories, I think that's a fair trade off for an attack that wouldn't normally miss, especially when the vry description goes onto say that successive fire makes evasion after the first shot pretty much impossible.
