I wanted to collect videos and articles comparing elements/programs side by side or over layed so you can directly compare them.     Lutz This one gives stats on quad lutzes performed by Nathan and Yuzu http://perform-live.com/blog/video-analysis-of-figure-skating/231-quad-lutz-what-else.html   Not sure how informative it is since it's so old but this also has these types of pics of Nathan's jumps from the Olympics https://www.nytimes.com/interactive/2018/02/16
