isn't this the way it should be????(preshuffled) since that would most mimic a B&M room. The dealer isn't constantley shuffling the cards throughout the hand. However, The constant shuffle premise actually makes the hand "more" random then the B&M preshuffle.

It already is many orders of magnitude more random than what any human dealer can accomplish before the heat death of the universe either way. But both continuous shuffle a pregen decks are equally random.

The downside to shuffling the deck once and keeping it for the hand is that it encourages hacking. As far as I can tell there is very little extra computation required to get a new shuffle for each card, so the sites should go with the slightly better alternative. If nothing else it soothes the nerves of paranoids.
