So because [USER=59679]McMeghan[/USER]  and [USER=5454]vapicuno[/USER] have started a new way to analyse viability rankings, I wanted to try it for a metagame whose VR has been very old (at least here on smogon) and has a decent sized playerbase. I have asked 21 rby'ers to send in their rankings and 15 of them have send them to me, which are [USER=123746]Sceptross[/USER], [USER=445293]HML am[/USER], [USER=327320]Aliss[/USER], [USER=265630]Amaranth[/USER], [USER=326944]roudolf13[/USER], [USER=122818]Prinz[/USER], [USER=224290]Heroic Troller[/USER], [USER=19]Hipmonlee[/USER], [USER=199297]Disaster Area[/USER], [USER=233818]Enigami[/USER], [USER=348930]Kaz[/USER], [USER=429040]Maya Chansey[/USER], [USER=356921]ErPeris[/USER], [USER=254408]Lusch[/USER] and [USER=424525]FriendOfMrGolem120[/USER]! Thank you!

Without further ado, here are the new Viability Rankings (how the subtiers are made, will be explained below):
[hide]

[I][B]S Rank: [/B][I]Reserved for [I]Pokemon which pose a very significant offensive or defensive threat, consistently harming or walling the opposing team. The roles these Pokemon can fulfill are crucial, if not mandatory, for RBY teams and these Pokemon are the best at their certain roles. [/I][/I] [/I]

[*]:exeggutor:

[B][I]A+ Rank:[/I][/B][I] [I] Reserved for Pokemon that are outstanding in the RBY metagame. These Pokemon pose a signifigant offensive or defensive threat to most teams. If these Pokemon have flaws, they are often outshown by their strengths. [/I][/I]

[B][I]B+ Rank: [/I][/B][I]Reserved for Pokemon who are very good in the RBY metagame, yet are somewhat inconsistent. These Pokemon may have flaws, but they have positive aspects which makes them stand out, making them valuable members of a team.[/I]

[I][B]D+ Rank: [/B]Reserved for Pokemon that are mediocre in the RBY metagame, but are decent enough to pose a threat at times, usually out of surprise. These Pokemon have a small niche in the metagame and are often not worth using.[/I]

Some explanations, informations, etc:

[*]I stole most of the format from [URL='https://www.smogon.com/forums/threads/adv-viability-ranking-ou.3503019/page-16#post-8115920']Roro[/URL] and [URL='https://www.smogon.com/forums/threads/adv-viability-ranking-ou.3503019/page-16#post-8116093']Vapicuno's[/URL] posts, so give them a like!
[*][B][COLOR=rgb(209, 72, 65)]Important:[/COLOR][/B] As roro said in the original post, he has decided to remove outliers out of the equation for the final ranking. That means I did not take into account the highest and lowest individual ranking for each Pokemon in their average (if multiple people were an outlier, I removed only 1 instance so sorry Sceptross and Amaranth!)
[*]The document contains two pages one with the outliers and one where i removed the outliers until porygon because at that point half of the playerbase stopped ranking.
[/LIST]
This second group ranking's statistics:
[LIST]
[*]Only HML am had the top 10 correct, although in a different order.
[*]Outliers didn't really matter that much in the end, but I still removed them just to complete.
[*]Amaranth was the only one to rank starmie over exeggutor, where Hipmonlee was the only one to rank Alakazam over Starmie.
[*]For all intended purposes both Rhydon and Zapdos and also Victreebel and Cloyster are ranked almost exactly the same.
[/LIST]
We can already see some big gaps between certain groups of mons appear, but lets also use the Vapicuno method to make it more clear. I encourage all of you to read [URL='https://www.smogon.com/forums/threads/objective-visual-mathematical-method-of-constructing-viability-ranking-tiers-test-data-adv-ou-2019.3649801/']his post[/URL], where he explains his method in a nice and clear way. So, in the two plots below one can find a graph where the average is plotted per mon (orange dots) for both the datasets. The standard deviation is also plotted, which is signified by the black error bars. The bolded black line shows if a mon is overestimated or underestimated, where underestimated means that they have a numerically lower rank than their average and overestimated is the other way around. So, a mon whose average is 11 but is ranked 9, is underestimated. This means that everything below the bolded line are overestimated mons and everything above underestimates. This is important to consider, because a shift from overestimate to underestimate will tell us that there is a (sub)tier shift.

[B][U]With Outliers[/U][/B]

At the bottom left, we can see 3 mons with Tauros being the lowest one followed by Snorlax and Chansey (The Big 3). Then we see 3 mons that have almost no Standard deviation and have almost integer ranks, which are Exeggutor, Starmie and Alakazam. After those 3, we meet Zapdos and his hard counter Rhydon with almost the same average and SD. After this we see a big gap, so these will for sure be the S and A ranked mons. Tauros, Chansey and Snorlax are all part of S rank, whereas Exeggutor finds itself in S-. Starmie populates A+, whereas his psychic brother Alakazam finds himself in A. Zapdos and Rhydon finish the A rank in A-.

Now that we know what is considered A tier, lets move on to the B tier mons. Here we first meet 4 mons that only differ by 0.5 in their average (Victreebel, Cloyster, Jynx and Lapras) and these will be A+. Then there is Jolteon followed by Slowbro and Gengar in A, although the difference between these are much larger especially between Jolteon and the other two. After this we move into C-Rank mons, which is just one rank with Golem, Articuno, Moltres, Dragonite and Persian. In D-rank we find Porygon (D+) and a lot of mons that only few people have ranked so I'll only include Hypno, Sandslash, Kingler (D) and Pinsir (D-) because a significant amount of players have still ranked them.

To me, these results appear reasonable. We have seen in SPL 10 that Exeggutor can be more easily dropped than the other Big 4 members and some teams function significantly better without an Eggy. We can also see that Starmie is a class apart and that zam is worse, but still better than the rest. We can also see that people also value Slowbro and Gengar less than they used to and that Vic and Cloy have been on the rise.

Because I'm not the most experienced RBY'er out there, I would appreciated if some of you can give some feedback if these ranks are correct or not. Also if you want to send in your own rankings, you can pm me here or on discord to tjdaas#5961 and I'll see if I can add them. If you have any questions, you can ask them as well! Also, sorry if I made a mistake here and there.
