Sorry, I guess I am a retard then.

True randomizing variables, such as the ones utilized in some major online poker software, take into consideration user action and time in generating the, let's say for arguments sake, river card.

If a player checks, folds, or raises it will manifest a different card on the river. So showing this "it would have been this river card" is arbitrary -- as it is VERY likely that the card would have been different if the user called, folded, or raised. The best RNG security uses this type of RNG to ensure that if someone does sniff packets or whatever the medium of compromising the system, that STILL, they will not be able truly know what the river card is.
