It appears to be for the release version; there actually two documents, one by Dick Wilson for Welles, where he briefly runs through the problems he saw, and then another by Welles, which elaborates on everything in detail. He doesn't really name many specific preferences since no score was done prior to Roemheld other than the temp track, but he discusses tone and intended effect often. For example:
"The preview title music was written by a first rate composer, George Antheil. Although not written for our picture at all, the temp title music had an atmosphere of darkness and menace combined with something lush and romantic which made it acceptable. The title music as it now stands is atrocious."
"SAILING MONTAGE: This whole musical section is unbelievably poor. Again our temporary track was 100% better. I cannot understand why some of the feeling we tried to indicate with this temporary music wasn't taken as a cue by the composer; but here, as elsewhere, he seems to have gone out of his way to create an effect totally different from the one I indicated. The temporary track, although pasted together in a hurried manner, had variety, movement, and romance. It conveyed the feeling of a journey -- a journey taken into a picturesque and highly-colored world. It had, besides this, a quality of satire. None of this is present in the sequence as it now stands. The rhumba treatment of "Please Don't Kiss Me" over Rita's dive is particularly painful."
