Lots of times it's your dominant foot. If you kick a ball right footed that foot goes in back. Push a Razor scooter with right foot, right goes in back. Both making you a regular rider.
ME I do both these right footed but I slide on ice/floor right foot in front. I snowboard right foot in front IE goofy.
So the old tests dont' always work but I am that rare odd ball statistic for those tests. Give it a try goofy sometimes it just clicks for you.
