About skilling

Skills increase everytime a skill event occurs. Each skill has different skill events that increase the skill, and a skill event may additionally be worthy or unworthy.

Skill events

Tactics

Worthy

NPC fires one laser shot at pilot, worthy if $skill_{pilot} \lt skill_{npc}$, unworthy if $skill_{pilot} \ge skill_{npc}$
NPC fires one missile at pilot, worthy if $skill_{pilot} \lt skill_{npc}$, unworthy if $skill_{pilot} \ge skill_{npc}$
Pilot lands one critical hit with laser against NPC
Pilot lands one critical hit with missile against NPC

Unworthy

NPC fires one laser shot at pilot, $skill_{pilot} \ge skill_{npc}$

Skill gain

Everytime a worthy skill event occurs, the respective skill will increase by the following amount (where skill_pilot and skill_npc are the pilot's current skill level and the NPC's skill level respectively):

$skillgain_{worthy}\left(skill_{pilot}\right)=\ \frac{1-\frac{\left(\operatorname{floor}\left(skill_{pilot}\right)\right)}{200}}{\operatorname{floor}\left(skill_{pilot}\right)^{2}}$

The formula for unworthy skill gains is not known, but the best known approximation is:

$skillgain_{unworthy}\left(skill_{pilot}, skill_{npc}\right)=\frac{skillgain_{worthy}(skill_{pilot})}{(skill_{pilot} - skill_{npc} + 1)^{1.3}}$
