The Optimal Shuffle

[paulish]

On the DVD Cheating at Hold'em, David Malek gives the following
Optimal Shuffle Sequence:
- -- --- ---- -----
1. Scramble
2. Box
-Cut the top 1/3 of the deck and put it on the bottom
3. Riffle Twice
(Bottom and top card of the deck should change on each riffle)
4. Box
5. Riffle Twice
6. Strip
(Take a portion of the top of the deck and place on table: 4-6 times)
7. Riffle
8. Cut
----- ---- --- -- -

-How does one determine that this Black Jack shuffle is the Optimal Shuffle Sequence?
-You might get a pretty random deck, but at the cost of time. This shuffle is way to slow for use in my home game. How many steps can you delete, between a quick Scramble and the Cut while not giving up to much on the quality of the shuffle?
-Any other standards out there?
