But, another 50% of reduction of time production must turn the 30h in 15h becouse, mathematically, if you do 30-50% you will have 15 and not 20, and so on for the others.. Take a scientific calculator and try.. Correct times, for example for the first book, must be 60h -> 30h -> 15h -> 10h -> 7h 30min or not?
