Ines It isn't usually a good idea to go pushing your data to where you would like them to be. A good way to determine natural spacing is to carry out a 'nearest neighbour' analysis.
If data are on a grid, the best spacing is 0.2 times grid size. This keeps single grid spacing separate from single diagonal spacing and so on.
