Okay so i could finally play this game again lol
I caught an Vulpix and that girl said
"Overall, your Vulpix is a decent pokemon"
"It's got excelent stats, how exciting"
According to this,
http://serebii.net/pokemongo/appraisal.shtml
The percentage of the IVs is between %50-%65 as the first sentence
and to the second sentence, it means the total IVs are 13-14 .
I truly didn't understand it now. If the highest is 15, shouldnt my vulpix be good then? but the percentage is VERY low
btw for my Pikachu it says
"Overall, your Pokémon simply amazes me. It can accomplish anything!"
"I'm blown away by its stats. WOW!"
So Pikachu is one of my best i guess
It also says that my Pikachu is gigantic
