Could you link to a specific moment where his Excel skills show? I have seen this video pop up from time to time and by clicking through the timeline all I ever see is him copying numbers from pdf's into Excel. Surely the whole "wizardry" aspect cannot just be the fact that he uses alt-tab and arrow keys instead of a mouse?
