Note that multiplying the three ''P''<sub>90%</sub> values for area, net pay, and hydrocarbon recovery does not yield a ''P''<sub>90%</sub> value for reserves; in fact, it gives a product corresponding to 98.7%! Similarly, multiplying the three ''P''<sub>10%</sub> values gives a reserves product that corresponds to ''P''<sub>1.3%</sub>, not ''P''<sub>10%</sub>.
