Random Number Generator weirdness

Here is a good candidate for investigation by the good folks at Silph Road. Here is my Raikou data: I've seen 22, caught 15. Not a single one has had over 89% IV's, although I have 3 with 89% IV's.

I have calculated that the odds of finding 22 random Raikous with not one over 89% IV's is around 2%.

By the way you may wonder how I know that the ones I didn't catch weren't over 89% IV's. The lowest CP for a 90+ CP Raikou is 1883, and all the ones I missed are below that. My highest CP capture is 1891 CP, but is is only 89% IV's (15/15/10).

Of the first three Raikous I had a chance to catch, one had 100% IV's (CP 1913, which I failed to catch), and one had 98% IV's (CP 1909, which I caught).

I have friends with similar stories. Are some phones just lucky?

You lucky guys should enter the lottery!

Or does that mean they have already used up all their luck capturing a virtual monster?

By the way, two of my catches were 71% IV's, one was 12/10/10, and another 10/12/10. This is the equivalent of 96% IV's on the other end!

Here's an idea. My phone is old and slower than most (IPhone 5s). If the IV's are generated by the server, might this affect the IV's that get handed out?

I play on an iPhone 5s as well and always seem to be the last one joining in on Raids. I've only seen 2 Legendaries out of all of them over 90% IV. Both Lugias actually. Caught a 91% 2039 CP and had a 2046 run from me 2 weeks ago. Never seen any others above that percentage and I even have a 100% capture rate on Zapdos, 11/11. I know because I have the CP charts for all Legendaries showing the minimum CP for 91%-100% IVs.

200+ Legendary Raids:
Never seen a 100
Never seen a 98
Never seen a 69
Never seen a 67

The bottom two are the worst possible ivs for Legendaries, btw.

ive got the same 15/15/10 as well as the following

14/12/15 91%
13/15/12 89%
12/15/11 84%
10/11/10 POS 69%

Im actually in a similar situation caught 14 out of 18 raikou and I can not get anything over 93% but I have 3 that are 93% one being 14/14/14 that I got today before this My highest cp I was able to get was 1896 so my guess it's that rng messing with us again.

RNGesus works in mysterious ways. I only ever caught 1 Moltres and it just happened to have 100% IVs. Haven't caught a single Raikou yet, raids around me are scarce

Same thing happened to me. I was 0/7 on Moltress then I caught a 100%

i hate you guys. Gratz

In a game with so many occurrences, it's easy to look for and find some patterns...

That said, and I have no way to prove this, and it would take a huge amount of data, I "feel" that overall for all players, everyday, everywhere, RNG is really random. BUT, for some players on some days, the randomness is altered. An example of hints of this (not an evidence of course) is doing mass evolves and getting the same moves over and over again. It's like there is some inertia in the RNG sometimes... frankly that would be a great idea by Niantic, makes the game more mysterious and makes us feel lucky or unlucky.

OK, I know it's probably just real random RNG, but... I want to believe

People don't understand rng and sample size. Everyone is trying to find a pattern or order to randomness when there is none. This is not surprising, however, because it is human nature to look for patterns; we don't want to accept randomness and that is why we cling to archaic belief systems and superstitions in the hope that we will be rewarded.
