Target Time

• The target time is the amount of time the game expects the battle should take. It is calculated by dividing the enemy's strength by your party's strength and adding 8 to the result. Your enemy's strength is calculated by multiplying the enemy's hit points at the start of the battle by the enemy's level and dividing this number by 16. This equation is repeated for every enemy, and then the results are added together to find the collective enemy strength. Your party's strength is calculated by multiplying your attack power by your ATB level and then dividing this value by the product of your ATB level and 3.5. This equation is repeated for each party member, and then the results are added together to find the party's collective strength. Both the enemy's strength and your party's strength are then plugged into the equation "Target Time = (Enemy Strength/Party Member Strength) + 8" to find the target time.
  
  

Actual Battle Time

• The actual battle time is the amount of time it actually takes you to finish the battle. This value is always rounded down and does not include any summon animations or preemptive strike animations.
  
  

Points Per Second

• Your points per second is, as the name implies, the amount of points you earned for every second of the battle. To obtain the battle's points per second, divide the "target time" you obtained in step one by 10,000.
  
  

Calculation

• Plug your "target time," "actual time" and "points per second" values into the following equation to obtain your total points for the battle: "Score = {[(Target Time) - (Battle Duration)] * (Points per second)} + 10,000." If you had a preemptive strike at the beginning of the battle, multiply the result by 1.2 to obtain your score.
