Emitters not pulsing at the same time.

[Sweeping Motion]

I have 8 basic emitters emitting a pulse. I'm wondering why would they not emit at exactly the same time to have the particles line up.
Anyone got any ideas?

Try disabling the Continuous Option in the emission tab.
When you enable it it will also emit particles within the duration of a single frame. When you disable it it will emit exactly on the start of a frame.
