  We report measurements of the action associated with center vortices in SU(2)
pure lattice gauge theory. In the lattice units the excess of the action on the
plaquettes belonging to the vortex is approximately a constant, independent on
the lattice spacing 'a'. Therefore the action of the center vortex is of order
'A/a^2', where 'A' is its area. Since the area 'A' is known to scale in the
physical units, the measurements imply that the suppression due to the surface
action is balanced, or fine tuned to the entropy factor which is to be an
exponential of 'A/a^2'.
