How do I single out which proposed stats are correct when getting multiple alternatives on the onsite IV calculator?
Example:
Gastly, CP 862, HP 56, 7k dust/8 candy to power up. Strong, blown away by HP.
Proposed stats by the calculator (A/D/S) are 14/6/15 or 9/10/15.
How do I sort out which one is correct?
How's your candy situation?
I've found the higher the targets CP is the more accurate. IF you're not hurting for Gastly candies I'm sure the calculator will be able to identify it as Haunter.
That said. Neither of those stats are particularly amazing. Even if you were to fully evolve if you won't get Shadow Claw.
Is it worth it? The choice is yours.
Either way it will be good for Alakazam solos. Easiest way to find out is powering up, hard way is using it in a battle where you can calculate that one combination will take one more enemy fast move to die than the other.
EDIT: Checked and you need to do 2 power ups to know which one it is. 9 atk combination has 876 cp at 35, 14 atk combination has 875.
If you choose to power it up a bit, the results will likely be narrowed down. Otherwise, I've heard that certain apps exist that will sync with your account to accurately calculate every IV value, though I'm personally hesitant to trust any such app, (I've invested too much time into my account to risk being banned).
Two ways:
1) Power it up
2) Evolve it
I'd suggest evolving it to Haunter to see if it's the 14/6/15, even if you are low on candies (but have enough to evolve it) because with the weather boosts to spawn rates, when it gets Cloudy you can likely find Gastly's every time. (They're like Pidgey's here when it gets Cloudy - it's like the Pidgey's are killed by the lack of clear skies and are resurrected as a Gastly...)
If that doesn't narrow it down for you, then power it up if you have the dust to try with. Personally, I'd risk it for a Pokémon as useful as Gengar - 7000 Stardust isn't nearly as big as it sounds thanks to the Weather Boosts and the 500 Stardust for attempting a Raid. And even an Attack 9 Gengar is useful at that level.
