These tables grew out of an attempt to ascertain how the values of two contending forces change as the fight goes on.  The offensive power of the stronger force is placed in the beginning at 1,000 in each case, and the offensive power of the weaker force at 900, 800, 700, 600, 500, 400, 300, 200, and 100.  These values are, of course, wholly arbitrary, and some may say imaginary; but, as they are intended merely to show the comparative strength of the two forces, they are a logical measure, because numerical; there is always some numerical factor that expresses the comparative value of two contending forces, even though we never know what that numerical factor is.  Two forces with offensive powers of 1,000 and 900 respectively may mean 1,000 men opposed to 900 men of equal average individual fighting value, commanded by officers of equal fighting ability; or it may mean 10 ships opposed to 9 like ships, manned by officers and men of equal numbers and ability; or it may mean two forces of equal strength, as regards number of men, ships, and guns, but commanded by officers whose relative ability is as 1,000 to 900.  It may be
