How drop rates work - my thoughts on it

[Navigata07]

hi @Below_Average_AC_Player
in that particular collection, my "missing item" is the (sorry if wrongly translated) spectometer. my actual distribution is (left to right) 24-0-13-20-20
so, even though is a rather small sample, i could guess that spectometer and "wide-angle camera"(?) are the rarest (though not equaly rare)
that somewhat confirms a suspicion of mine: there is always a "rarest" item, though not the same for everybody...

Thats exactly what I've been saying. It's done at random for the most part, and can even change as you progress through the game. In the beginning, nocturnals were super rare, but now its the astrograph that's super rare for me (IR telescope collection)
