After doing the math again and measuring an actual table, the distance from the edge of an MFT to the edge of a hole is 61mm
(And according to Grev's PDF, 60.9mm)
Here's the math: (at least the way I look at it)
Horizontally an MFT = 1102mm
11 holes @ 20mm with 96mm centers.
So that's 10x96mm = 960mm + 10mm +10mm = 980mm
1102mm-980mm=122mm / 2 sides = 61mm from the bottom edge to the bottom of the holes.
And the same vertically = 718mm.
7 holes @ 20mm with 96mm centers.
6x96mm=576mm + 10mm + 10mm = 596mm
718mm-596mm=122mm / 2 sides = 61mm from a side edge to a column of holes.
