It works differently for eggs. 3 IVs come from the parents and 3 from the MTRNG (seed) That's why there's a greater chance of you finding good IVs via eggs than in the wild (assuming you have decent parents).
You're welcome.
I explained that already. Choose method 5 (standard seed)/gift Pokemon in the main window not the time finder. Look at frame 8. Those are the IVs from RNG (your seed IVs).
