IVs - 100% vs 0%
How much stronger is a 100% Pokemon compared to a 0% Pokemon? How do we quantify the difference in performance?
Answers
is the truth IVs dont really mean anything in performance wise, any lvl 40 with several high iv pokemons know this, the main difference comes from increasing the lvl of the pokemon, but ofc having higuer IVs will give you higuer CP which is better for the current and old gym system so this is why you want higuer IVs plus are nice to have
Perhaps Niantic will get rid of CP mechanic someday and will let IVs work like main games, so better to invest in higuer ivs ones
You wont notice difference at all, the only time you will notice is if the pokemon is lvl 30 or lvl 39 and even that the damage is sometimes 1 more, HP increase wont be enough to stand one more quick attack either
IVs in pokemon go mean nothing just for have higuer CP this isnt main games, so unless Niantic say otherwise IVs dont tell you performance even the CP dont even does, and that even comes too from prodigination and trainertips
A 100% Dragonite is about to fight a 0% Dragonite on Pokebattler...we'll see what happens...3000cp. DT/O. Go! Most of the questions we ask the internet can always answer--probably why Niantic moved to cooperating raids, we really just want to high 5 our bros b/c we beat a Snorlax boss...we don't really want the Snorlax
TL;DR - is there a difference? Yes.
But not one that is significant enough that you could notice only from looking at gameplay, and therefore there's no need to worry about IVs unless you choose to.
It's not like 15 attack IV is going to shave 10 seconds off in a gym battle or 15 defence + stamina keeps your HP in the green while 0 would have your Pokemon in the red.
/end TL;DR
It depends on the base stats of the Pokemon, because IVs are only additive increases, plus what you're battling against, since damage also depends on your opponent.
An increase of 15 attack is theoretically more useful on a Pokemon with lower attack when it comes to calculating damage, because of the bigger relative increase.
Take Shuckle for example, with it's base attack of 17. An increase of 15 to 32 attack would almost double it, 32 compared to 17 is an 88% increase in it's attack stat (32 / 17 = 1.88), whereas on a Mewtwo, an increase of 15 attack from it's base attack of 330 is only a 4.5% increase. But because of damage rounding, these values don't necessarily result in an equal increase of damage.
For example you're battling against Snorlax with 190 base defence, and you use Rock Throw (12 base damage).
With 0 attack IV then one Rock Throw would deal:
0.5 x 12 x 17 / 190 x 1.2 = 0.644 damage which gets rounded to 1.
While with 15 attack IV you'd deal
0.5 x 12 x 32 / 190 x 1.2 = 1.212 damage which gets rounded to 2, doubling your damage.
On the other hand if you battle a Steelix, who double resists rock moves and has ridiculously high defence, a Rock Throw's calculated damage is 0.187 with 0 attack IV and 0.353 with 15 attack IV both which result in 1 point of damage, no difference in damage.
But if you just want the theoretical value, work out the relative increase that each IV has to the base stat and then multiply these values together.
So still using Shuckle as an example (17 base attack, 396 base defence and 40 base stamina), if it had 15 in all IVs, it would theoretically be 2.686x stronger than a Shuckle with no IVs, since it could theoretically deal almost double the damage of a 0 attack IV and also have more HP, which might not seem like much before considering you take 1 HP of damage every quick move due to Shuckle's defence stat combined with dodging.
(32 / 17 x 411 / 396 x 55 / 40) = 2.68627451
Because Shuckle's stats are so extremely low, you get such high values, but for most Pokemon, a 15 increase to any stat is much smaller, usually around a 5-15% increase, that there is no noticable difference in effectiveness.
15 attack or defence will usually only add / subtract a few points of damage from a charge move and have no effect on quick move in most battles, and stamina results in the same HP increase for all Pokemon if they are the same level - usually 11 at 30, 11 or 12 at 39.(stamina IV x CPM), but that's comparing it to a 0 IV Pokemon. Average IVs are 8/8/8 which is only a 6 HP difference, which might not make a difference if your Pokemon gets hit by a charge move before it faints anyway.
Edit: just posted this BEFORE the post above was added, just look at that haha
It depends on the Pokémon involved and their base stats. For example, blissey has a base stat of 129? and 510? Having a 0% would roughly have those values when maxed and a 100% would have an additional 15 in each stat, making the stats 144 & 525, vs 129 & 510 @ 0%. In blissey's case, attack is important to have when damage is calculated, the stats of an attacker and a corresponding are used as a ratio.
A perfect Iv attack blissey gains nearly a 12% increase (129 + 15/129) to its attack whereas a perfect hp will give blissey a 3% increase (510 +15/510) to its hp.
As you can see, attack ivs are significantly important to blissey, compared to hp. Therefore, it depends.
I heard a while back, months back, that the "performance difference between a 100% and 0% vaporeon is about 6%" unfortunately I don't have a source at the moment :( I'll see when I get back if I can find something
I posted an example calculation a week ago. It is very simple: (BaseAttack+0) / (BaseAttack+15) * 100% results in a number around 93%. So by maximum Attack stat (15) you gain 7%. However, the rounding of the move damage may often make this irrelevant.
In defense, multiply the defense and stamina total stats and you find typical difference of 16% longer life when those IVs are 15 compared to 0.
My God...

How much better is a 100% than a 0%?
About 2 seconds and 10 hps.
But that's only one simulation that you chose to use... and only resulted in a two seconds difference. It affects faster moves more and levels of the pokemon come into affect. Every battle is different and people have tried to figure out these breakpoints where you can do one extra damage. https://articles.pokebattler.com/2017/05/30/damage-breakpoints/
Once again just one example but seconds matter in raids.
I wish IVs had more of a noticeable impact.
I mean, the team leader says that a 0% pokemon "won't make much headway in battle" and that a 100% pokemon "can really battle with the best of them". If the actual difference is just a couple seconds then why do the team leaders hype it so much? I'm saying they should make IV have a greater impact so the appraisals aren't fake news.
