I think you're kinda missing the idea of index time boosting. The semantic of this (as I remember Chris Hostetter explaining) is "this document's content is more important than other document's content".
By doing an index-time boost that's the same for all your documents, you're effectively doing nothing to the relative ranks of the results. Not quite sure what Luke is doing here, but using &debugQuery=on will give you the actual scores of the actual documents. And if you're doing anything like wildcards or *:* queries, shortcuts are taken that set the scores to 1.0. If none of that helps, I'm out of my depth <G>..
