I suggest doing castings of both of her hands.

While somewhat humorous, that is a pretty uninformed statement. I would hazard to say that a majority of people coming out of HS these days do not know how to learn at a college level (I didn't) but there are classes as college that do teach you how to learn (effective reading, how to study for various tests, how to think critically, etc.). After taking a study class my sophomore year in college I went from being a 2.0 student to a 3.5+ student (I'm now back in college going for my MS degree and am at 3.95 for my grad classes). Lots of this is due to knowing how to study, which I was taught when in college.

I used to be a cop and I did a LOT of traffic stops. In training and certification to use a radar gun they train you to look at the vehicle whose speed you're going to measure and make an estimate of their speed before using the radar, then compare the results. This was a practice in Washington state but I would not be surprised if it is common everywhere. After a while you get very good at estimating speeds and find yourself generally guessing the correct speed +/- 1 MPH. When you write your subsequent traffic stop summary you include a sentence stating that your observed a vehicle that appeared to be speeding and your visual estimation followed by the radar measured speed. This gets the officer trained to look at what's being measured rather than just sitting there with the radar pointed back over his shoulder waiting for something fast to come through which then builds credible speed estimation and descrimination into his testimony and also gets past the problem of accidentally radaring the Cesna 150 that flew overhead at 80 mph while erroneously attaching that speed to grandma who was doing the speed limit. In short, anybody who does a lot of anything reasonably well gets good at it - cops do a lot of speed estimation and get good at it.

Hehe! I know of it too because I'M THAT KID!!! HAHA 10023R!!! send mail go out post dammit! send dammit! TEACHER, CAN YOU HELP ME SEND THIS EMAIL!?
