Total Efficiency Coefficient, (T.E.C.)

T.E.C. Is the closest possible approximated measure of energy expended in any biochemical and or socioeconomic process from start (A) to finish (B) generally portrayed in calories and represented as a percentage in decimal form.

i.e. A boat carrying a load from South Africa to Beijing has a stand still value of (Xcalories) @ point (A)=Xcal. divided by the total calculable energy in calories expensed in “fuel”, “labor”, “payload loss” and “mechanical breakdown” used upon reaching point (B)=Xcal. where {Xt.e.c. = (A)Xcal. / (B)Xcal.}.

*Xt.e.c. = Total Efficiency Coefficient, (T.E.C.)

Soviet Efficiency 

A phrase that decribes any system, operation, or action, where the beaurocracy serves to create more problems than the problem it was created to solve.
