Looks like a table of contents, something I personally can't confirm. If it is do remember that Weekly Young Jump has no connection to Weekly Shounen Jump, other than having the same publisher. Young Jump is intended for an audience up to ten years older than Shounen Jump, there is not necessarily any connection between business practices. There is no guarantee that Young Jump orders there TOC based on fan poll rankings. They certainly do not cancel as many series as Shounen Jump, nor start as many new series per year. Even if the TOC is ranked by popularity, the ranking may not hold any meaning.
I do not know if Young Jump's TOC is a ranking but. I do not think it is, assuming the above list is the TOC. The most popular series in the magazine are clearly evenly spaced between the front, middle, and back. Usogui, Contach, and Kingdom are near the front. Zetman and Tough are near the middle. 81 Diver, REAL, and Rozen Maiden are near the back.
