I'm hoping what I'm seeing is just confirmation bias and not how the game actually works, so I'm asking and hoping more analytical minds can assuage my fears. It seems like, with eleven Observatories, quite fewer than 11% of my rare astronomical events are automatically being observed. It was my assumption that each Observatory would add 1% to my chance to auto-observe, and so at 100 Observatories I would automatically generate a starchart (and some science) from every event (and have lots of them!). Isn't this right?
Does building more Observatories increase your chance to auto-observe, or is the base chance the limit?
