The only benefit I can see of cluster ranking over straight ranking is that with cluster ranking the PNM's may keep a more open mind ..
ie with 6 #1's each seems to be of the same weight of "want" as opposed to the mind set of 1 vs 6 with #1 being "better" than #6.
Another benefit is time. It's sometimes impossible to convince a PNM that since she can accept 5 invites tomorrow it doesn't matter who she gives the 3 and who she gives the 4.
