Im just wondering what the chance of finding a at least one shiny is if I keep resetting the radar until my repels run out.

P(shiny) = (14,747 - 40 n) / (2,621,440 (41 - n))

P(shiny) = chance of a shiny n = length of the chain

Chain length: 40 Shiny Chance: 0.5%

It would be the same chance as regular chaining, but the Max Repels would simply eliminate the chance of your chain being broken by random wild encounters. Also, the chance of finding a Shiny goes up 0.5% every five encounters from forty.
