In reply to Kemics:
Mostly 3 as I remember but all 1/2 inch bolts so massively over engineered - they don't want bolts failing on the most famous route in the world. I think the foreign teams were the only ones equalising the bolts - connect them yes, equalise with a cordalette etc, no. Lead line fig8 into one bolt, clove hitch into the other. Makes life easier with the volume of stuff to have 2 or 3 strong points rather than one master point.
