  We report on the numerical analysis of the area correlations in spin foam
gravity on a single 4-simplex considered by Rovelli in PRL 97 (2006) 151301. We
compare the asymptotics and confirm the inverse squared distance leading
behaviour at large scales. This supports the recent advances on testing the
semiclassical limit of the theory. Furthermore, we show that the microscopic
discreteness of the theory dynamically suppresses and regularizes the
correlations at the Planck scale.
