"[Question] Has IVs gotten generally worse lately?"

#PokemonGO: I'm not sure if I'm just really unlucky, but lately I've been getting mostly <50% IVs on Pokemon I'm catching. I've noticed this change since the bonus event. Since PokeStop drops were nerfed, I thought maybe the likelihood of good IVs might've also decreased.Out of my last 21 caught Pokemon:1 was 67-79%3 were 51-66%17 were 0-50%Is this happening to anyone else?Edit:In the past week, I would estimate that I caught about 200 mons, but only kept a small handful that weren't terrible. I transfer mons pretty much right away, basically as soon as I find out they have poor stats. I didn't count the IV distribution of my previous 200 mons before transferring, so I can't give an exact number, but almost all of them had bad stats.21 IS a very small sample size but I didn't pose my question solely based on that, but also based on my unrecorded 200 mons. I only mentioned the 21 mons in my post because I still had them on hand from my pokewalk last night.Since there's a lot of mixed answers from everyone, so I'll just chalk it up to unlucky RNG! via /r/pokemongo http://ift.tt/2gcUCuN
