My First thought is:
Even if you have a "Free Network Node" , don't change the percentages unless you have an Effic. Rating of +4. (Assumption: The Value of Labs = Econ @ 50/50).
Calculation (Econ/Labs) w/ Free Network Node:
Effic. = 0; 50/50; 1*(0.5) + 1.5*(0.5) = 1250/1000.
Effic. = 0; 40/60; 0.84*1*(0.4) + 0.92*1.5*(0.6) = 1164/1000.
Effic. = 0; 30/70; 0.68*1*(0.3) + 0.84*1.5*(0.7) = 1086/1000.
Effic. = 0; 20/80; 0.52*1*(0.2) + 0.76*1.5*(0.8) = 1016/1000.
Effic. = 0; 10/90; 0.36*1*(0.1) + 0.68*1.5*(0.9) = 954/1000.
Effic. = 2; 50/50; 1*(0.5) + 1.5*(0.5) = 1250/1000.
Effic. = 2; 40/60; 0.92*1*(0.4) + 0.96*1.5*(0.6) = 1223/1000.
Effic. = 2; 30/70; 0.84*1*(0.3) + 0.92*1.5*(0.7) = 1218/1000.
Effic. = 2; 20/80; 0.76*1*(0.2) + 0.88*1.5*(0.8) = 1208/1000.
Effic. = 2; 10/90; 0.68*1*(0.1) + 0.84*1.5*(0.9) = 1148/1000.
Note: This holds TRUE, only if the Value of Labs = the Value of Econ! Question: Is their ever a case, where this isn't true? And how much more valuable is Labs over Econ? And, what - about Psych?
