How does the slider on your main screen relate to the number of labs you have, etc.
For example, I have 2 labs (8 tp) and one civ capital (24 tp) on my homeworld.  Should be 40 tp (what is a tp?).  The research on the top right is 17 (17 what? I'm not sure, its not labeled).  From the domestic screen, my research rate is 70% and i have a total of 28 bc spent on research.
How do these numbers relate to one another?  If I build another lab on my homeworld, I guess my tps will increase by 8, but what does that mean?  will more research get done?
Thanks in advance.................
