At this moment when  you change the production wheel there is no direct way to see how the allocated research points result in research completion turns. The research percentage and actual numbers of research points generated is being shown. 

To see whether there is an actual change in the number of research to complete turns, you have to close the govern economy tab and open the technology window.
PS: After you close the Govern window the "research turn remaining" tooltip (top right corner of the main view) is not properly updated.

You have to ping-pong between these two windows to actually fine tune your research rate.

The feature i wish to see is something that will show in the govern/economy window the research completion turns for the given distribution of the production wheel.
