Trinity Force works off of Base Attack Damage (excluding bonus damage), not Attack Damage (including bonus damage) or Bonus Attack Damage (excluding base damage).

Which means the only damage that gets increased by Trinity Force is your 45 + ( 2.6 * Lvl ) AD (89.2 at 18)

With just Trinity Force and lvl 18 (119.2 AD) with Rank 5 Mystic Shot:
 * Correct Total
 * Mystic Shot Damage: 115.0
 * Mystic Shot Bonus Damage: 119.2
 * Trinity Force Damage: 133.8
 * Total: 368 Damage
 * Incorrect Total
 * Mystic Shot Damage: 115.0
 * Mystic Shot Bonus Damage: 119.2
 * Trinity Force Damage: 178.8
 * Total: 413 Damage
