Quarry Spawns Formula

[LyraParry12]

I'd love to put some numbers on how spawn chances in the Quarry change over the years - the wiki just gives a flat spawn chance for each type of rock, but also says that the game "attempts to spawn 7 different items" from the given table in year 1, with that increasing by 2 each year up to a max of 16. Wouldn't that mean that once you get to year 7, you have a 16/18 chance of getting any rock type *every day*? I feel like I must be missing something, not only bc that's way too easy, but because the flat spawn rate for iridium is given at 0.0133%. ???? If anyone is able to tell me how the game actually calculates this, I will be forever indebted to you <3

I think that means that it will roll the chance for various things each day, and once seven items have spawned (in year one), then it stops checking for more new stuff. So you would max out at seven new things per day in year one - but they could all be ordinary rocks on a given day (it doesn't guarantee seven different things). Adding two more per year just means that in year two, you could get up to nine items to spawn.
