=== Volatility  ===


This attribute is the chance of the crystal taking damage upon every activation cycle, and it is shown as a percentage. One must be cautious to interpret the value correctly because it is displayed incorrectly. For example, a Volatility of "0.1 %" is actually 10%, meaning that each activation cycle the crystal has a 10% (1 in 10) chance of receiving damage. Likewise, a "0.2 %" Volatility is actually 20%, etc.

This is especially confusing for some combat crystals, which may be listed as a 1% Volatility.  What this actually means is a 100% chance of damage per shot.  It also means that the life expectancy of these combat crystals may be calculated exactly, because every shot will always damage the crystal.  (Currently, all faction combat crystals have a 1% Volatility, i.e. a 100% chance of crystal damage inflicted per shot.)

The formula for determining average life expectancy of a crystal is simple:
The formula for determining average life expectancy of a crystal is simple:


<blockquote>'''Life Expectancy (in cycles) = Structure Hitpoints / Volatility / Volatility Damage''' </blockquote>
<blockquote>'''Life Expectancy (in cycles) = Structure Hitpoints / Volatility / Volatility Damage''' </blockquote> [NEEDS CORRECTION]


One may then multiply the expected cycles by the cycle time to calculate a crystal's life expectancy over time.

The Plagioclase Mining Crystal I has a Volatility of 0.1%, which means that for every cycle there is a 10% chance that it will receive damage. The amount of damage it receives will be the Volatility Damage value of 0.025 HP. It will shatter when its total damage reaches the Structure Hitpoints value of 1 HP.

This means that, on the average, the crystal has a life expectancy of 1 / 0.10 / 0.025 = 400 cycles.  With a standard (unbonused) strip mining cycle time of 180 seconds, one may estimate that a crystal will endure approximately 72,000 seconds, or 20 hours, of constant mining before shattering.

Tech 2 crystals will last, on average, 200 cycles or 10 hours of constant mining with the standard cycle time of 180 seconds.  Note that bonuses from an Orca or Rorqual which reduces cycle time by up to ~33% will cut this life span to 7.5 hours.
