PF Source. Trouble with Path and SpeedByIcon

[pwinter]

I have a stream of particles leaving the source, and using PositionIcon"pivot" to start particles at a single point.

I have added a SpeedByIcon operator, which is linked to a path.  The particles follow the operator and path nicely.

BUT, I don't want the particles to cling to the path, but spread out A LITTLE BIT around the path (divergence?), once they disperse from the source. 

I can't find any information to make this happen.

Any help would be most appreciated.

Thanks for reading and replying.

More to my post...

I would be happy if the particles grew for 30 frames before reaching full size.  Much like all the other particle systems, which have a growth operator.

PF source is very frustrating as there is no extensive manual on how to use it.
