For the purposes of psionic abilities, the mechanics sometimes call for the calculation of base competencies specific to psionic characters:
Precision is a measure of the psionor's accuracy and finesse.
Calculated from: Telempathy|FOC or Telekinesis|FOC (i.e., Telempathy + .5 FOC)
Force is a measure of the psionor's raw power.
Calculated from: Telempathy|WIL or Telekinesis|WIL (i.e., Telempathy + .5 WIL)
Capacity is a measure of the psionor's ability to multitask, determining the complexity of their powers.
Calculated from: Telempathy|INT or Telekinesis|INT (i.e., Telempathy + .5 INT)
When a power calls for a Telempathy or Telekinesis BC without specifying which of the three is required, assume it means Force, as WIL is the primary attribute for psionic characters.
