There were significantly shorter... Here are the original instructions, copied directly from the AHA website:
Ferment at 45-55o F (7-13o C) for four weeks, and perform a diacetyl rest at 60º F (16º C) for 48 hours. Slowly lower the ambient temperature by 3º to 5º F (1º to 3º C) daily until you reach 38º -40º F (3º -4º C). Transfer the beer to a secondary fermenter and continue to lower the temperature to 30º -37º F (-1º to 3º C). Lager for seven to twelve days. Rack to keg, or add bottling sugar and bottle and allow to carbonate at 50o (10o C) for two weeks minimum.
