The trick is that "I pop out from the same location" to me becomes "the monster expects you to pop out there, is watching right there, and sees you before you attack".Exactly. To those who say you shouldn't be able to hide and shoot multiple times from the same location, would you allow it if the rogue was hidden behind the monster? How about if the rogue was behind the monster and the monster was engaged in melee with two other PCs? Three?
On the other hand, if you are popping out at different spots, you can get the attack off before the monster can spot you.
And yes, sufficient distraction would make it possible to do that. How much? I dunno, roll some dice.
