My source[0] says the lower bound for full overhand shuffle is number of cards squared, so less than 3000 shuffles for 52 cards. Upper bound around 5000.

- tridentboy 6y agoWell, it seems that his point still stands. Overhand shuffle is terrible for actually shuffling a deck of cards.
- strogonoff 6y agoAssuming 4 shuffles per second, 3000 shuffles would take about 12.5 minutes, while 10000 shuffles would take more than 40 minutes. One of those sounds feasible during a break on a casual game night. Of course, those numbers apply only if the shuffle is done literally—I personally try to mix individual cards by letting one hand’s batch cut in-between the other’s (and I think I’m not the only one)—but I’m still curious where did those 10000 come from.
