Sweepiness limits of 190 disallow builds like Voodoom's and Yanmega's, which I don't think should be considered "ridiculous", especially considering both are balanced at best. In fact, Latias has "Fantastic" SS and so does Jolteon; the latter is pretty much a glass cannon while the former is weak to U-turn and Pursuit and has Dragon STAB. I'm not convinced, then, that "ridiculous" would apply to ~200 Sweepiness ratings on a Pokémon with more problems than Latias, potentially the same level of difficulty as Jolteon, and certainly more issues than Voodoom.
It's also worth noting that the September stats show Choice Scarf Genesect having more usage than all Latios combined. Basically, that set alone is in the top 15 O.o
