The unmodified total values for each branch in the list should be greater than the empire potential shown in red background in the upper right.
A, B, C = Weapons, Hightech, Energy.
A+B+C = D
D = (Whatever number added up.. A+B+C!!! )
D > R (D has to be greater than R!!)
What is R???
R = Terp (Total Empire Research Potential.)
Make sense Remuguis???
