It is also known as the “Specific Behavior for the Templar Rule of 72 pdf”. It outlines the ideal behavior of a knight. It was, however, adapted for use by active, primarily military, knights, rather than cloistered monks.
For example, the fasts were less severe so that they did not interfere with combat. Later, it was expanded to include 609 articles, notably covering such things as hierarchy and justice within the order. This page was last edited on 17 October 2017, at 17:19. The choice of number is mostly a matter of preference: 69 is more accurate for continuous compounding, while 72 works well in common interest situations and is more easily divisible. There are a number of variations to the rules that improve accuracy. The formula above can be used for more than calculating the doubling time. If one wants to know the tripling time, for example, simply replace the constant 2 in the numerator with 3.
To estimate the number of periods required to double an original investment, divide the most convenient “rule-quantity” by the expected growth rate, expressed as a percentage. Similarly, to determine the time it takes for the value of money to halve at a given rate, divide the rule quantity by that rate. 20 years for the value of a unit of currency to halve. 4 the value in 48 years, compared to holding exactly the same investment outside the policy. 1, 2, 3, 4, 6, 8, 9, and 12.
The approximations are less accurate at higher interest rates. For continuous compounding, 69 gives accurate results for any rate. Since daily compounding is close enough to continuous compounding, for most purposes 69, 69. 3 or 70 are better than 72 for daily compounding.
For lower annual rates than those above, 69. 3 would also be more accurate than 72. In the SVG version, hover over a graph to highlight it and its complement. File:Doubling time vs half life. He presents the rule in a discussion regarding the estimation of the doubling time of an investment, but does not derive or explain the rule, and it is thus assumed that the rule predates Pacioli by some time.
12, e in 12 anni sarà raddoppiato il capitale. 12 results, and in 12 years the capital will be doubled. 8 years would be only about 0. 002 off, where using 72 to get 3. 6 would be about 0.
72 could be adjusted by 1. To compute the E-M approximation, simply multiply the rule of 69. 23 years, where the actual doubling time at this rate is 4. The E-M rule thus gives a closer approximation than the rule of 72. Note that the numerator here is simply 69. As long as the product stays constant, the factors can be modified arbitrarily. 79 gives 72 on the numerator.
Alternatively, the E-M rule is obtained if the second-order Taylor approximation is used directly. 72 beyond fixed-rate growth to variable rate compound growth including positive and negative rates.

Classifier matches are held by each affiliated club. The matches consist of a 3 stage course of fire. Details for each stage, including walk-through and videos are available for each.
