Oh. For those unsure what IV actually is, it's actually very simple. A perfect Pokémon has maxed 15 on all three stats. That's 45 points possible. 45/45 x 100 = 100%.
Every IV value you ever see is evenly trickled down from there. I don't need a calculator to tell you that 44/45 x100 = 97.8
43 = 95.6
42 = 93.3
91.1, 88.9, etc.
The reason I tell you this. Is because the actual spread between those stat points varies slot. You get Pokémon that can perform noticeably different, even sitting at the exact same IV.
The simple team leader appraisal messages really don't give a complete picture. You read a 1 stat blown away (15) and think it'll be whatever 80s, maybe 91. Run it through and it's 96. Or excellent stats (14 or 13 maxed) getting a higher IV reading then if that exact Pokémon you were checking had blown away instead.
I'm actually more interested in exactly how cp corelates. Example, I have 2 98 snorlax, one hp/atk best the other hp/Def. I worked them to the exact same spot on the arc curve. Yeah, twin snorlaxes right? Wrong. The atk 15 one came out higher.
Just really interested in seeing more. I'd love, for example, a third 98 (atk/Def best) and work THAT up too.
