Geez, I feel like I need to write a fully-sourced research paper in order to back me up and get through to you. I'll be back in a day with a ridiculously long entry.

Until then, I'd like to point out that there is hard evidence for the Frigates, considering I pulled all of my points regarding them from the Codex and codex-supported pages. Also, scanning is limited, just please trust me on this one. I'll explain better later.

On the other hand, how did my baseball analogy not make sense? You're trying to hit an infinitely small point (relative to planet size) from millions of miles away while it is spinning and shooting through space in a circular orbit at thousands of miles an hour. And that's not even factoring the fact that the rounds aren't just going through empty space, they are acted upon by everything in the system that has either gravity or electromagnetic fields. Not to mention the atmosphere it has to travel through and the coriolis effect of the rotation of the planet. Even future computers have limits dude. It's safe to bet that if the Reapers can't pull it off, then some random VI isn't going to be able to either.
