Front Panel Designer/Express, Schroff vs. Fischer

I'm designing a 2U panel for a tube preamp I'm building. When you want to add the rack holes to the panel it asks you if you want Schroff or Fischer. When I select one, and compare it to the other I see no difference at all.

What are the differences?

The actual postion of the holes used to fit the panel to the rack are identical. But the additional holes used to connect the panel to an enclosure are slightly different I believe.

Cheers

I thought that might be the case, but I saved the file with both formats, and had them open in 2 tabs, and zoomed really far in, and switched between tabs and could not see a difference.

Simplest way to check is to click on each hole and read its parameters.
