My average error was 5.2 for the first try. But I got ripped off, because the mouse slipped on the line convergence, leaving me off by 13.4 units. :mad: I think I did pretty good. I used to work at a sign company, and we did a lot of work just based on visual estimates. ---

Oops, I didn’t realize it had you go through three times. Final score, including that screw up, is 4.3 ---

I’m impressed. My average was 18.9. Still, very cool. ---

I’ve done it like 12,438 times, trying to beat my friend’s 2.6. Not doing so well. But now I’m a pathetic game junkie with no future. Feel bad for me.☹ ---

I got a 7.58 overall, but I got much better at it as I went along - I did the convergence one perfectly on my third try, and my score on the third go-through was about 4.7. ---

I got a 4.05. I wonder, though… The “bisect the angle”, “point equidistant from the sides” (which is really just “bisect the angle” again) and “make a right angle” ones will depend on screen settings (pixels don’t always have the same aspect ratio). Do they correct for that? ---

After three tries, my best average is 3.90. I found that I actually did better when I spent less time actually “eyeballing” the positions. My initial positioning was usually the closest, and I just wound up farther off target if I thought about it too hard. 😛 My best performance was on “bisect angle” and “circle center” – on those I was generally within 1 unit or so, and sometimes even less. By contrast the parallelograms repeatedly kick my ass. **Lobsang** , I don’t think it’s possible for something to be homework if it has a high score table. 😃 ---

3.94, first (and only) try. I thought that was pretty bad until I saw the score distribution, not to mention the numbers being posted by all of you losers. 😉 [Next page](https://boards.straightdope.com/t/this-rocks-eyeballing-game/472425.md?page=2)
