Not probably more, DEFINITELY more.

I would take off the fork and measure it on a flat table. The rake is the distance from the steer tube center line to the hub center when clamped into the drops.

Clamp an unlaced hub in the dropouts, and set the fork down on the table. Using wood blocks, metal blocks, books, or what have you, prop up the steer tube so it is parallel to the table surface. Now you can measure the distance from the side of the steer tube closest to the table and farthest from the table to the table top. The average of these two numbers is the height of the steer tube centerline above the table.

Then measure the height of the center of the hub axle (use the edge where the QR cap is screwed on) to the table top.

Now subtract the hub height from the steer tube centerline height, and that is the rake. If you make all the measurements to the millimeter, you will have an accuracy at the end nearly to the millimeter.
