Reading these forums, I'm struck by how many commanders scan strategically - Don't scan the moons, or just scan the stars unless they are a certain class. Listen to the unexplored on the system map to determine if they are worth visiting. These are all great tips for efficiently finding the most interesting and valuable bodies to maximize the volume of space you can cover in a session.
Unfortunately, none of that pertains to me. That's because...
I scan everything. Every star, planet, or moon in the system must be scanned with a detailed planetary scanner. Then, it gets worse: I look over the results of my scans, and if a planet looks unusual - temperature, atmo composition, or class, I'll go and eyeball the planet. Obviously this does terrible things to my efficiency, and I waste precious minutes dropping into and crawling out of gravity wells, but I don't care. That's why I'm out there.
Right now, I'm spending up to half an hour scanning a single system, and sometimes longer if it's a large or complex system.
Horizons will make that longer, I'm sure. I'm certain I'll want to take an even closer look at some of these planets. It's going to be awesome, but it isn't going to help me rack up the klys.
"To stand upon the surface of an unknown world and look beyond it, to the next one." That's me.
Any other completionists out there? Or am I alone in my brand of madness?
