Let us assume that Kelin was rolled in November 2003(not to bad assumption for extremely long-lived char who doesn't play all too often). We know that this was about 66 weeks ago, so Kelin would average 10 hours a week. If that is not enough for a caballed character, you are demanding too much.

However, if we assume that Kelin was rolled in January 1995(I wonder if CF was up already at that time, the records on officials do not reach that far), we get about the figure you said a bit more than an hour in week(1993 would be more accurrate in the one hour assuption, but I think CF isn't that old).
