Gonna class this as a bug.
If I navigate to a GPU category and select (e.g.) 2x SLI, then view the rankings for any of the benchmarks, it still includes a bunch of the single card results until I hit "2x" again in "number of cores"
......and the "mixed" rankings make NO obvious sense. e.g..... 1x 2x, 2x, 1x, 2x, 1x, 2x, 1x, 2x, 1x, 1x, 2x, 2x
