I'm not sure why, but no one else seems to be updating their IV calcs yet. I have put all the Gen 6 Pokemon in along with changes to old Pokemon (denoted with (X/Y) at the end) that we know about.
The base stat "estimates" seem to be good because we haven't had any invalid ones yet. There is one or two new characteristics that I haven't figured out yet, but the siestas one is already added.
Also, Hidden Power is only 60 attack power now, regardless, so ignore that result. Fairy type may or may not be a Hidden Power attack type. If it is, then the Hidden Power Type calculation could be off.
