Wow, nice work! I guess we should focus on integers from now on, that should make things a lot easier. I tried -68.000, 72.001 out of curiosity and got 99%, so I'm guessing it's at the integers only or needs to be even closer.
And I'm surprised about no Mars version of what we're doing. We do have almost 400 moon bases to the 150 or so mars bases, but that still seems like enough to get things going, maybe not as fast as us but better than going on your own.
