>>55727446Normally in pokemon you get a patch of grass that has a set amount of pokemon with set chances that will add up to 100%, like 3 25% chance mons, 2 10% chance mons, and a 5% chance mon
But in sleep you can have anywhere from like 3 to 100 possible mons available, and so you'd need some way to sort out what the actual chance for a pokemon to appear is
What those screenshots were was a simple way of doing so. Each pokemon has a weighting, or rate in the graph, then normalising (not sure if that's the correct term) it so each available weight proportionally makes up 100%
