GSC pre-loaded sets that have Hidden Power on them don't use the correct DVs for that set (with the exception of Marowak). If, for example, I pick "RestTalk Zapdos" (which has Hidden Power Ice), it loads with all DVs at 15 (whereas in fact that set has to use a Defense DV of 13, to get Hidden Power Ice) and you have to adjust them manually to get correct damage calculations against it. And if I pick "Curse Sweeper Machamp" (which has Hidden Power Bug), then it again loads with all DVs at 15, while in fact it has to use a 13 DV for both Attack and Defense, screwing up both sides of the damage calculator. I can understand if it's too much work to make manual selection of Hidden Power automatically adjust the DVs, but pre-loaded sets should have the correct DVs or they're highly misleading.
