My definition of flawless is slightly different. I expect IVs of 31 in every stat unless you're going for a good Hidden Power. Anything less I'm not really interested in, sorry.
Yeah, RNG is very difficult; I've been trying to IV breed flawless PKMN and usually get close, but still haven't succeeded yet. I hear catching flawless PKMN (catching with RNG) is easier so maybe you should give that a try first. I'm probably going to do the same.
