I was gonna say this belongs in _plant problems_...but it isn't really a problem, is it?

Don't panic if a bit of tap root pokes out. You don't actually mention the size of the pots, but I'd wager that you still could have gone another week in that last pot, minimum.
Just because the tap-root is peeking out it doesn't mean that it's time to re-pot. The tap-root is always on the move, looking for new space, the roots coming off of it will still need time to spread out to reach virgin soil.
Let the plant tell you what it needs, they usually will droop a little as they start to feel the need for more space. Or, gently lift the plant out of the pot to take a look when you think it might be time. (do this when the pot is pretty dry)

I've had tap-roots coming out of 5-gallon pots within 2 days of a final transplant during flower, no issues.
