* <p><b>How to interpret the values in the registry?</b><br>
* The digits of the result: 5 has to be subtracted from the first digit (in decimal representation), 4 has to be subtracted from the second digit,
* 3 from the third etc.
* If the result of a subtraction is negative, 10 has to be added.
* Examples: 64 => 10 APM; 40 => 96 APM; 8768 => 3336 APM; 38 => 84 APM</p>
