[Sidefx-houdini-list] particle trail

Hi there,

Does someone know how the Birth Probability works?

What I'm trying to do is have particles birth from other particles in a 
way that the new particles form a evenly spaced trail.
So a fast particle would birth more particles then a slow one in a way 
that both would leave the same amount along the same distance.
The amount of particles to birth per point/sec would be the length(v) 
divided by distance between each step.
But I can't seem to get the probability to take these values.

Anyone any idea.. or a better method?
