I've been playing around with the sparse pyro combustion model and have a few question about the emission of smoke by flames.

1 - I was under the impression that, when emitting smoke eg. in flame range 0-0.5 from a clear (full 1.0) burn field with a flame life of 2.0 there should be no smoke emitted at all within the first second?
However, my flame field immediately drops down to values below 0.5 on the outer borders, even without any diffusion/dissipation going on. Hence theres smoke coating my flames from the start.
How could my burn source (values are either 0 or in range 1-2, sourced with max) approach values as low as 0.1 in the flame field on the second simulation frame? Maybe blurring by the advection? Or am I missing some field interaction here (temperature)?
I have attached a small example scene to showcase the issue

2 - I also wanted to use some noise inside a sop solver to vary the flame density emission rates. While I could import the field with Dopimport Fields I could not find a way to apply that noise outside of the sop solver (bind it back to the dopnet).
