Unsurprisingly, the top 5 of UU are Steelix, Claydol, Clefable, Rotom, and Hitmontop, with the order just being slightly rearranged each month. Those seem to be the top 5 UU Pokemon. I do wonder why Hitmonto['s usage is so consistently high with two of the top three Pokemon being 100% checks to its most common set, TechTop (and slightly further down the line, Venusaur and Weezing also stop it handily).
