What is the hard-coded maximum number of eggs you need to hatch in order to get a 6IV from scratch, and by that I mean you don't start with a 6IV Ditto?
Give me a number. If you say, for example, 200, then there must be something in the code that makes it impossible to hatch 200 eggs and not get a 6IV, that's what maximum means.
If it's random, and the chance of any single egg being 6IV does not increase with the number of previous eggs, then there is no limit, it can go on for millions of eggs if you're unlucky enough. The chance of succeeding once in a series of attempts approaches 1 but never reaches 1. This is basic math, if you don't understand, you're underage.
Go on, anyone who says "it only takes [specific finite number] hours", prove it CANNOT take longer than that.
