Interesting observation. So if some positions are being integrated from the "universal results" servers, it could account for partial results if an import call fails.

If every SERP is created by a complex interaction of several hundred servers, your idea about a bug makes sense to me for the very short pages. I don't see that being the case for these 8 and 9 entry pages, however. They are intentional and repeatable.
