in Delih, the reduction is exponential for each scholar housed, in the madrasah there is room for 20 scholars, which avoids having to build several mosques. For example if I want to research chemistry, with 12 scholars, it takes 22m30s that I divide by 1.125 ^ 12 which gives 22.5 / 1.125 ^ 12 = 5.47, that is 5 m with 28 s. If I build 2 madrasas that time is practically half.
1.125 is the average
