A NPV is the result of a mathimatical equation involving approximatly 15 multiplication variables.  In a mathematical series involving 15 multiplications, you only need to improve (increase) each variable by about 4-5% and you get a NPV result that is way over double the old one. If you increase each variable by closer to 10% you get about 5-6-7 TIMES your previous NPV calc.  As an industry expert you would know that, one would think....
