If you would like to see a more statistical based approach to a real life example, I made a surface level statistical analysis on podium placing and yoyo choice for the online Scales Open 3 yoyo competition.
I focus on things like construction, width, weight and even brand choice. I think its very interesting to see how the trends (and also the deviant data) on those types of yoyo characteristics look on a real life example of a competition.
