you really only need 3 flawless IVs to get a hex-flawless baby, the more flawless IVs the better, but as long as you fill in the right IVs for the right Parents in RNG reporter, RNG reporter will take care of the inheritance and give you the right seed. If you reverse the parents you will spend 10 hours getting the exact same result with wrong IVs and wondering what is going wrong ... Like i did when i first tried to RNG and kept getting a perfect Magnamite with the wrong IV spread ~.~
