“six or seven riffle shuffles are sufficient to produce a well-shuffled deck. …fewer than five shuffles is notably insufficient”

Apparently mathematicians have determined that to actually randomize a deck of cards the above must occur. So, I guess that (when playing poker) might explain the high occurances of pairs and trips if a deck is not properly shuffled. This leads to my question… When in play, is it a true fair game if the cards are not shuffled at least six times?

Anyway not sure if this information is valuable, but it is good to know.
