====== Skill tests ======

Skill tests are an important part of the eXode's game-play. These tests are performed in two steps:
  - Estimate the Chances To Pass (CTP)
  - Roll a d100 (generate a random number between 1 and 100) against the CTP

If the roll is above the CTP, the test is failed, if it is below the CTP, the test is passed.

===== How to determine the CTP? =====

The Chance To Pass is determined from the character Skill rank and the Test's Difficulty (TD).

  * CTP = 100 x [ (Skill - TD) + 50 ] / [ TD + 50 ]

The CTP gives a chance in percent, with a minimum of 0 % if the Skill rank is equal to (TD - 50), and a maximum of 100 % if the Skill rank is equal to (TD x 2).

The Test's Difficulty value is usually 30 for Easy difficulties, 50 for Normal difficulties, 80 for Hard difficulties, and 120 for Elite difficulties.
