In the IV calculator, what do the multiple lines and percentages mean exactly? Each line in the output is one possible IV set that would create the values you entered. The percentage after each line of output is what you get when you add all the IVs in that line and divide by 45 (15+15+15). It's a quick way of seeing how good the Pokemon is, because it's hard to tell at a glance if a 10/10/10 Pokemon is better than a 12/12/7 Pokemon unless you use percentages. Above the lines of output are the average percentage, and also the range of percentages from the minimum in that list to the maximum in that list, so you can compare that Pokemon quickly with others of the same type to see which one you are most likely to want to evolve without having to power up each one a couple times to narrow down their IVs to the exact values. credits
/u/LastSasquatch Evolving a pokemon does not count as "powering up."
The IV calculator gives me a big range in percentage? How do I narrow it down? You can narrow it down by levelling up your pokemon once, then entering in the new values and hitting compare. There are a lot of combinations of IVs that can produce some sets of CP and HP at a given level, but the subset of these which also produce the new values for CP and HP at the next level is generally going to be much smaller. The only way to narrow down IVs without using dust and candy is to read data being sent between the client and the server. A guide for that was posted here.
