Ralf Dujmovits, 3-time Cho Oyu summiter, notes that for a strong climber to get to the "hump" area can take another 30 minutes. The source of the dispute was that Himalayan chronicler Elizabeth Hawley, whose Himalayan Database is used by online databases like AdventureStats, "unrecognised" his Cho Oyu ascent in Spring 2005 (15 years after summiting). Hawley based her decision on an interview with Hinkes, and on other team members. Hawley agrees Hinkes reached the summit plateau (as does list), but questions how Hinkes could have been on the “technical” summit for certain, if he could not see it. Hinkes logged the expedition's 30 April 1990 Cho Oyu ascent in the 1991 American Alpine Journal (AAJ), as well as the expedition's ascent of Shishapangma 12 days later on 12 May 1990, but he notes they climbed Shishapangma's central (west) summit (the true summit is circa two hours further on). Hawley's biography notes French expedition leader Benoît Chamoux: unhappy with this, as she did not credit Chamoux with Shishapangma either (Hawley had compelled the famous Himalayan mountaineer Ed Viesturs to re-climb Shishapangma for the same reason, which he did). Hinkes would not climb with Benoît Chamoux, or any of the French team members, again. Hawley does not use the public accounts of the non-French team members. Czech team member Josef Rakoncaj photographed Hinkes on the summit plateau of Cho Oyu (Hinkes with his usual photo of his daughter held out), and states Hinkes summited in his book "Na hrotech zeměkoule" (co-authored with Miloš Jasanský, 1993). Italian team member Mauro Rossi lists the 1990 ascent of Cho Oyu in his public resume. Climbers with several Cho Oyu ascents, have disputed Hawley's main Cho Oyu summit criteria, "Did you see Everest?" (which is obviously unhelpful in Hinkes' case given the poor visibility), and the incorrect behaviours it is creating. Hawley's Himalayan Database records 3,681 ascents of Cho Oyu of which 18 are "unrecognised" since 1960, despite the difficulty of finding Cho Oyu's "technical" summit, and that older expeditions considered the summit plateau as sufficient. Chamoux's 1990 Cho Oyu expedition comprise seven of these "unrecognised" ascents (including Alan Hinkes), while a German commercial trekking expedition, led by Günther Härter, who summited Cho Oyu just 19 days after Chamoux in 1990 (and also in very low visibility, as recorded by the Germans), comprise another six. The dispute is noted in many Hinkes interviews. He highlights
