How random is a shuffled deck?

I do not know every part of a professional dealer's shuffling methods but how do you really confirm that when he/she shuffles that the cards are randomly distributed?

This is interesting from a theoretical perspective but from a practical viewpoint, if a dealer's mechanics are sound then scrambling the deck, and going through the four-step procedure of shuffle, shuffle, riffle, shuffle will provide a deck that is random enough .

After all, poker's been played this way for years, without any major issues attendent to the relative randomness of the deck. I don't see any advantage gained by shuffle tracking at the poker table, except under circumstances where the dealer is sloppy about his work.
