am i cheating?

[mostsmooth]

usually when im sitting in a seat in front of the dealer, i watch him and notice the bottom card(s) when he picks up and organizes the deck after the wash and before he starts his shuffle (theres not much else to do). last night i noticed a particular dealer that when he shuffled, the bottom card usually stayed on the bottom during the shuffle process (3 shuffles) and i could follow it toward the center of the deck after the cut. there were 3 or 4 occasions where this bottom card appeared on the board during that hand (holdem).
i realize this dealer has a flawed technique, but am i cheating or simply taking advantage? if i had a better talent for estimating the number of cards in the cut, i would have an even bigger advantage.
i also realize if anybody else knew i had a better than normal chance to know if a card was coming, theyd be mighty upset.
