My tut bought a 3.6m dorm (13th dorm) and it gave me 320k which is 11.2% of the cost. Then he bought a 4.5m dorm (14th dorm) which gave me 341k which is 13.2% of the cost. When he bought his 15th dorm at 9m it gave me 584k which is 15.4% of the cost. It is a neat update in that it gives cash although it's not much at all. It tells you who is active. Also, the more expensive the dorm is, you get a higher PERCENTAGE of that dorms cost back in cash it looks like. Even if each dorm gave the same percentage of its cost, the pupil still gets more cash whenever the tutor buys a more expensive dorm but you are getting even better which is a higher percentage of the dorm cost as well.
So I guess it's possible that the last set of dorms could have a super higher percentage of cash transference. If the last dorm gave a transference of 30% then that would give the pupil 150m but who knows what transference percentage will be for that. I guess everyone can ask for a refund now for all their tuts that upgraded before this update
Also note that the % of dorm cost increases increasingly (meaning that it is exponential on this region at least) which is a glimmer of hope that the upper dorms will give a nice amount of if infact the percentage does increase increasingly for the remainder of the dorms. We know there's an exponential increase in the cost of the dorms from the first dorm to the 32nd dorm, now if the percentage transference remains exponentially increasing with the remainder of the dorms then you may see a super sexy last dorm cash transference.
