's computus, which was described in the reference books of 1922 and 1992.
Klinghammer's computus was restored by Joseph Flores in 2006-2007 who published a book on it. Flores' book was the subject of critiques, in part because of its non scientific approach and its many gaps. Critical reviews have been published in the Mitteilungen of the Deutsche Gesellschaft für Chronometrie # 113, pages 471-472 of the "Bulletin of the National Association of Watch and Clock Collectors" (ISSN 0027-8688), vol. 50, n.4, August 2008 and in the NAWCC fora.
