No, he had a ~90min video that was purely overviewing how he uses excel. Wasn't really about finance anymore, and isn't available on youtube.
There's one from him that might be adequate in my public folder on keybase.
Doesn't look to be the one, its analysing eBay in Excel, he navigates Excel well but its in no way a tutorial, there's no description to how he's doing anything. Nor is it particularly advanced.
Do we have to install keybase to see it? I'm not familiar with it, so hesitant to install till i have some time...
