How well do you judge angles and centers?

I posted this a while ago, must be well over a year, anyway ... thought it might be interesting to some of you to take this test a few times. It is a little lengthy, don't give up on it, there are multiple puzzles before you get your results.

Have fun :thumbup:
 
3.63
163.3

Had most trouble with finding point equidistant to edges of triangle.

Finding centerball was solid!
 
6.7 avg error
111 seconds

I'm sure if I took my time with it, I could easily get lower. I've been a draftsman for years, I see angles every day.
 
6.1 but that included a 64 that was recorded when I inadvertently lifted my finger off the mouse (and it was on the easiest test -- center of circle!)

Without that I was at 3.2

220 (seconds?)
 
Average error: 5.02
Time taken: 138.2

How many times did the guys that scored 3 play? That's pretty good.
 
Error: 2.70

Time:145.76 seconds

2nd run through

Error: 3.02

Time: 120.6 seconds

Oddly I think I did the best at finding the point equidistant to the triangle edges, all my errors on those were less than 1, which seemed strange since as I was doing it they seemed the most difficult. Would have liked to have done a little better on finding center ball, wasn't bad though. Parallelogram one is the one that got me.
 
I did it once this morning and posted that score. I did it again just a bit ago and got a little higher, just over 4, but I was going quicker too.

I am on a 24" monitor which I'm sure helps a lot compared to someone trying this on a mobile device.
