Retimed at dispatch: blocks are measured against the time you chose, not the published slot. Moving a departure before the flight is a plan, not a delay.

The phases add up to 32,899 kg burned; the tank readings taken off blocks and on blocks put it at 32,476, 423 less. The table uses the phases, because the on-blocks reading is taken as the flight ends and often lands a moment early, before the taxi-in burn has registered.
