lets say i want to research 10 technologies with a base research time of 2 turns each. 

In first case i have 100% research speed, so it will take me a total of 20 turns to finish all of them.

In second case i have 150% research speed, so i SHOULD only need 15 turns to finish all of them. Alas, i still need 20 turns.


Even cranking up the research speed to 190% has no effect on my actual research time needed in this case.
