Mega pin 7 to pin 8 spacing: 160 or 150 mils?

Hi all,
I'm reading

which says the pin-spacing between pin7 and pin8 on the Mega is 160 mils.

Then I'm looking with Eagle at the BRD file from:
http://arduino.cc/en/uploads/Main/arduino-mega-reference-design.zip
and it definitely seems that pin7 is at (1800,200) and pin8 is at (1650,2000) - so the distance would be 150 mils?

what gives?

The MARK function depends on your grid settings. Change your grid to 1mil and you'll see it is 160mils.

Please have a look at:

Uno reference design is 160 mils.
Mega reference design is 150 mils.

Okay... thinking back to when the 2560 was released I remember this coming up.

The board file was wrong. I don't know if it is intentional, but the "reference designs" always seem to have some minor issues in them.

Here's the 1280, 160mil:
