124 expeditions, of which 70 put someone on the summit. 316 summits (265 by members, 51 by hired staff) and 6 deaths, among 735 members and 109 hired staff recorded.
Summits count member records: someone who summited twice on one expedition counts once, someone on two expeditions in the season counts twice. Claimed (unrecognised) ascents are excluded and disputed ones included, as in the database's own statistics. Hired staff are only recorded when they went above base camp.
