Does the game previously played influence the amount of shuffling required to ensure a random deck? But the bigger debate is that my wife prefers to deal two cards at a time so as to make the dealing go faster, while I prefer to deal the cards one at a time even though it takes longer. My preference for one card at a time is entirely based on the belief that it creates a more random distribution of cards, a cleaner deal. The short answer is; random is random, and how you deal has no impact on that. Every set of cards is just as likely to show up as every other whether you deal one card at a time, 5 cards at a time, deal clockwise/counter-clockwise, or just deal as weirdly as possible.
