One comment on the global ranking graph ... Looks like we don't have room to keep the column abbreviations of C4 xx, WL xx and BS xx with the triple groupings of WOTM. So why not just Gxx Wxx and Bxx? It will save space and is equally unambiguous.

PS. I figured you probably don't need two decimal places, either. Is that OK?
