Those of you that calculate your fuel economy and compare it to the display value, how do the numbers compare for the Highlander Hybrid?

For my 2006 Honda Civic Hybrid, through over 16,000 miles, the display fuel economy averages 1.3 % low. I believe most people say the Prius display reads high. I was hoping that the Highlander Hybrid would also read low as I prefer to be pleasantly surprised when filling up at the pump, but I would imagine that it is more in line with the Prius.

I'm still on my first tank.

Thanks.
