Nice. I appreciate the insult.
Didn't know it was you but reading it gave me the feeling of reading about superman. With claims like this it's good to say where the info was found. My Grandfather once told me "Believe none of what you read and only half of what you see".
No offense to you but I take the "trust me I was told by someone but won't mention names" stories with a grain of salt.
As far as the Mifune video, what I see Mifune do in that video clip at 1:55 is to hit the line perpendicular to his opponent's feet with a Sacrifice Throw. That line of off balance is a basic Judo principal. I saw nothing to show otherwise. Great timing and execution! The Hiza Guruma he does at the end is nice!
I'm not debating what you see since I don't understand what you are teaching so could you explain what you are seeing in the video and how Mifune's throw would differs from the average Judoka?
