"It would take 100 WILD CATCHES to get all the Unowns!"

#PokemonGO: With 26 different forms of Unown (assuming ? and ! aren't released until Gen3), it would clearly take more than 26 wild encounters and catches to complete the Unown medal, because you'll inevitably get duplicates. But how many?So I just did some math...Assuming 26 forms of Unown (A to Z), with equal likelihood of spawning, it will take on average 100 CATCHES to get all 26 forms in the wild!By the numbers: Average # of catches = 26/26 + 26/25 + 26/24 + ... = 100.2 (26/26 to catch your first Unown, then 26/25 for the average time it'll take to catch your second new form of Unown, then 26/24 for the average time to catch your third form after you've caught two unique forms, and so on. These can be added due to the additivity of expectations.Some other stats:You might feel like you're halfway there once you've caught 13 out of 26 Unown forms. But you'd be grossly mistaken. The likelihood of duplicates increases exponentially as you catch more, such that by the time you have 13 different letters, you'd only be about 17% of the way there!The true halfway point is once you've caught 23 unique Unowns! The last three will likely take you just as long to find as the first 23.Better hope that trading comes out soon! Otherwise, one Unown a week means you're just shy of two years away from catching them all. Oh right, and by then we'll have ? and ! to catch. Happy hunting?! via /r/TheSilphRoad http://ift.tt/2kDFDvJ
