Step Acuity

Step AcuityPlease help me with a little science experiment.
Measure your Step Acuity (SA) and report it here.
Your SA is the number of steps before you hit a mark that you know whether you will hit the mark with your right or left foot. As you are walking down the street, choose a mark (a line or a spot) on the ground far in front of you, and say "right" or "left" out loud the moment you realize which foot is going to step on the mark, and from there count 1, 2, 3... until you hit the mark. Do you have an SA (i.e., mostly the same outcome every time), or is the number of steps highly variable?
No cheating, this is not a competition. Just honestly report back, SVP.
The hypothesis is that everyone has an SA, meaning the number of steps is highly invariable, and that SA is normally distributed. H2: The SA is different between those who played football (soccer) as a child and those who did not.
Also, feel free to report how many steps before hitting the mark you know that you are not hitting it at all (i.e., it's right in between left and right foot). Have fun.
