Well a single distance 1 is 3 1/16th I check (or 7.78cm) so each FTC give you just a tad more than a quarter of the tool to work with. This means that you. Go 1/8th inches with 2 FCTs. That on the distance side is a 3rd from the 3 movement.
Distance 2 is 4 15/16" so a single FCT makes that an 8" move and a second one gives you a total of 11 1/16th move in a turn. Out of a possible 12" with just a B-Wing. . .
