Surviving Mars: Specialization: University
Colonists gain 20 training points / sol at 100% performance (without martian adaptability or other techs). To graduate from university you need 300 training points so 15 sols. (Sanatoriums are set to cure at 200 "training" points.)
Martian adaptability is +100% point gained BEFORE performance is taken into account. So you can get 40 training points / sol at 100% performance with the tech and add another 50% of that on top with 150 performance to get 60 pts / sol. So the fastest they can graduate is 5 sols. You see how performance and tech snowball here because performance is not computed from base gain.
