I wouldn't put too much weight on it...

I tried it without much effort on my so-so Dell desktop display and got 59. Tried again on my RMBP with even less effort and got 14. However, I did have trouble in the same places both times so it's certainly demonstrating something.

I'm also using a Dell display. Maybe I should fiddle with the settings a bit.
