Try and use your other senses (not smarts) to determine when to shift. Feel and sound should be key, and use your lights to assist in your alert to shift. As the christmas tree begins to light up, shift. Don't wait until it reaches the end, if you do, you have missed your shifting point.
This has been my experience. The evidence is in how you're pushed back into your seat when you shift.
