WOW!!! that is an amazing pass. i have been experimenting with a couple of passes myself (herrman and classic) and i think your pass is great! it does look like a cover pass which is basically using the top card as cover by sliding the top card a fraction to the left (for left handed persons) and gripping it between the crotch of the left thumb while executing a "classic pass" motion with the rest of the deck below it rather than a herrman pass. I have tried using a cover pass but i find it too cramped in the hand but have found your stealth pass to be looser and has a more relaxed look about it and covers the pass beautifully.

Thanks very much for a great pass.
