From my experience Intuition(3)'s not required - by again using the center horizontal line AI quirk, you know that ~3 turns after hitting them with a rocket, at least one'll be right in front of you even if you can't see them. On v0987 you have the 50% miss chance, which changes this considerably, but waiting 'till you can see one has worked for me just fine, and at least you know that if you miss him, there's a better chance there'll be another one behind your original target than on any other horizontal line.
