The Temporal Smooth operator works best on fully cached particle data. Operators that inject forces into the sim (ex: Path Follow) will influence the result of the smooth operation...so your best bet is to create a reference sim (Birth Flow - Flow Update) and smooth that. In the next build I will also add an option to remove velocity from particles, so that even force operators won't influence the smooth result.
Also your sim has an extremely small timestep (1/32)...so that vastly increases the number of sampled points, thereby reducing the effect of the smoothing algorithm by 32x. I guess in that case, 100 max iterations is not enough - in the next build I'll unbound the max iteration value, so you don't need to stack operators, you can just crank up the iterations value. But really there's not really a reason to have such a low time step in a setup like this.
A workaround in the meantime is to increase your time step, and then after you cache your particle data in the Temporal Smooth operator, disable the Path Follow operator.
