so heres One Weird Trick that Sim Folk Don’t Want You To Know

add a pop speed limit, and set a minimum speed

i found with default boid stuff in pops that particles can stop too easily, which ruins the look

if you don’t allow the particles to go below a certain speed, you get much more of that bird like motion
