Before revision:  We calculate all these quantities analytically . Some of these quantities show apparently counterintuitive trends of variation with the qualityof kinetic proofreading. We interpret the origin of these trends .
After revision:  We calculate all these quantities analytically . However, we arugue that its performance is evaluated better in terms of the translational fidelity and the speed with which it polymerizes a protein. We define both these quantities and calculate these analytically. Fidelity is a measure of the quality of the products while the total quantity of products synthesized in a given interval depends on the speed of polymerization. We show that for synthesizing a large quantity of proteins, it is not necessary to sacrifice the quality .
