The issue, I think, is that the pieces of pre-gouged cane are not all straight; there are 3 possibilities:
1) the piece of cane is straight and outcome is 0.60 mm.
2) the piece of cane is not straight, it has an upside down U shape, in such case the outcome is less than 0.60 mm.
3) the piece of cane is bent, has an U shape. Usually in this case the piece of cane jumps off the bed of the machine and gets broken; if the bent is not very pronounced, as to the piece of cane not jumping off the bed of the machine, then the outcome might be either 0.60 mm or a bit thicker (depending on the machine).
