You may very well be right. The 1990, 1995, 2000, 2005, and 2010 Expeditions all had a 127 day schedule. The 2010 is the only one I have the logistics for and the War Spur Shelter is not listed as a scheduled stop. The schedule quite possibly had been "refined" by then. The 1975, 1977, and 1980 Expeditions were the shorter ones at 109 days. I imagine those were quite tough.
