Plan around the timer you actually see.
Use the current-timer mode once a queue is running: that timer already includes the speed bonuses applied when it started. Do not apply those bonuses a second time. Base-time mode instead divides a base duration by one plus the total speed bonus. The optional instant reduction is a separate one-off cut, not a speed stat.
Example: a 24-hour base duration at +100% speed becomes 12 hours. Four hours of speedups leave eight hours. A +100% speed bonus halves the duration; it does not remove all of it. Alliance helps and timing-dependent skills are excluded unless you enter their effect yourself.
