The term yardstick refers to what is a normal response. It really has nothing to do with a yardstick and can be used in many situations. A yardstick is a measurement that has been tested over and over and than that measurement becomes the standard.
Say the yardstick for a reaction time is 5 seconds
Meaning that is what a normal healthy person can do it in.
Joan has the reaction in 4.8 second. Well she is on the the bell curve and did better than the yardstick test measure.
Umm Flicker your wrist as your side arm moves ... Just think of it as you playing catch with a Frisbee.
You'll need to stick your thumb out, thumbs up style, and make a peace sign with your index and middle finger, making sure your palm is facing the sky. These are the three fingers you'll need....
