(that is measured using gsharp's rapsoden-sjunger.gsh score)

There are indeed some more duplicates, arising from split points
returned from FIND-SPLIT-POINTS differing by one part in 10^8 or so:

    1: CLIM-INTERNALS::FIND-SPLIT-POINTS returned
         (0.03709000980332888d0 0.16700945980421777d0 0.167009459804218d0
          0.3339371876264945d0 0.6123851602108852d0 0.8777177045678732d0
          0.8777177045678737d0)

    1: CLIM-INTERNALS::FIND-SPLIT-POINTS returned
         (0.20963359401083448d0 0.2096335983836628d0 0.6517729758960513d0
          0.6517729766787337d0)

maybe these should be tested for equality in the remove-duplicates
call in find-split-points using an epsilon of some magnitude?
Removing these four effective duplicates would reduce the quarter rest
design to a union of 24 areas.

Cheers,
