First, the official pokemon company explaination of the lifetime encounter method AND no statement by them saying it was bugged. Second, the sufficient sample size after all this time shows the average number of encounters for a shiny is nowhere near as high as full odds with a 3% chance of MM odds.
Also it was literally one faggot on twitter who posted the 3% thing. And data miners got it wrong 3 times this gen already. If you wanna do nothing but stare at eggs hatching, then go for it. But stop lying to others who want to do something else
