Is it just me or is that font a mess? The insides of the '11' are 3.8m apart. Adding the overhang of the second 1 (0.3m) and the width of the vertical lines of both 1s (2 * 0.8m) gives us 5.7m. Yet the outsides measurement is displayed as 5.6m.

Same for the 10: Adding up the space between the characters (2.3m), the width of the 1 (0.8m, just the vertical line) and the width of the 0 (3m) gives us 6.1m, yet the outside measurement is 6.0m.

Am I missing something?
