This is probably a mistake because, let's face it, no matter what I say in here people will be angry and shout at me but: the 3% stat is for both Master/Apex Predator, i.e. the text should read "Only 3% of matches for all Platinum players in Apex Legends have them going up against a Master or Apex Predator". The only distinction between Master and Apex Predator is the reward the get at the end of the season, the rest of Ranked treats them as exactly the same. (Entry costs are the same, grouping restrictions are the same, they matchmake the same, etc etc). The omission was simply a mistake on my part.
To clarify another critique made here: If a match has 30 Plats and there's one Apex Predator in the lobby, we count that as 30 games when calculating the 3% stat above.
I'm sure the people most angry about the stat will say "I run into Preds far more than 3%", and that is probably true for them, but it is not true for the system as a whole. If you play on a low population data center as a Platinum player, yes you will run into Master/Predators a lot more than 3%. On any single night I cannot guarantee that you as a Platinum player will not run into Master/Predators more than 3% of our games. But taken across the entirety of Ranked, our data is clear - this is not a problem that happens too often.
Of course I also understand that doesn't make you feel any better when you're the person who runs into an Apex Predator in your lobbies. We are planning on doing changes so the experience doesn't feel as bad for you, but as mentioned in the blog, that will take a bit longer to come.
