18, I could have done better but didn't want to put in the time or the work. Interesting though.

I did this last week and got 37 on the laptop, a score that I was not too happy with so I did it again this morning on the desktop, with it's nice, big, non reflective monitor, and got 14.

I must admit that my 61 horrified me, but I did it on a laptop when I was tired late at night. I'll have another go sometime.
