Particles per face are either too many or not enough I've set up a particle system that needs to have exactly one particle emitted from each face on the emitter mesh. However, the "Particles/Face" setting is apparently not working. When it's set low there are many faces not emitting particles, yet when it's set high enough that no faces are without particles there are also many doubled-up particles overlapping. 

The particles are bricks, so they are not animated, but I don't want holes in the wall or doubled-up geometry. Is there a problem with the "Particles/Face" setting, or am I misunderstanding what it does? How can I get just one particle per face?
You could emit the bricks from vertices, make sure that you emit exactly the same number of particles as the emitting mesh has vertices (121 in this case):

 


from verts



Emitting from faces with the grid option selected creates a box of emitted particles.
