To each their own. I count duelers twice, and racers once. On some racers (such as PKI's Racer or PKD's Rebel Yell) I keep track of forward and backward laps separately, but count the coaster once for my track record.
See
http://www.gregleg.com/coastershrine/viewTrackRecord.php?userID=1 to see what I mean. Note that Kennywood's Racer, or Cedar Point's Gemini, are listed once each; Rebel Yell is listed once but as separate LAP counts; and Twisted Sisters is listed twice.
(And yes, I *DO* plan on opening that track record counting page up to the public at some point in the near future. One of the cool features is that each user can choose any of the 3 counting styles listed above on a per-coaster basis :) )
