Oh, wait, no it isn't. I would find it more notable and realistic if the little details changed over 8 years. It is natural for real memories to change over time and become faded.
If someone is going to try and pull off a scam, they are going to rehearse over and over and over what their story is. They will make sure nothing changes. the story becomes ingrained in them.
Davis has told the exact same story, with all the same details in 2003, 2004, 2005 and now 2011. Of course his story would be consistent. I would actually bet if the police executed a search warrant of Davis' house they could probably find a note book with the whole story written out.
