I guess that's true, but in the time you're searching around for someone with a 0 IV Magikarp, you could be checking in the Battle Institute, or just breeding the old fashioned way ;)For time travel breeding. I need to see which IVs will be passed down from which parents on the next egg. I have a 6IV Magikarp, so if I bring the child of the 6 perfect and 6 null to the IV checker, he'll tell me which are which. I can check the IVs using an IV calc + Battle plaza whatever, but just having the NPC tell me saves a lot of time.
