if we set Sub-Steps to 2 instead of 1, it appears we get 1/2 the Stoke particles as a result. This does not seem like it would be desired, no?
we are expecting sub-steps to result in simulation accuracy improvement or finer fluid motion details, but not affect the count of Stoke particles.
You are right, and it usually working ok.
Unfortunately, I don’t have TP in my Max 2013 on my laptop. (But I fixed another bug in Stoke when loading missing plugins) 
I am sure it is related to TP because it seems to work well when emitting from geometry for example.
Once I get the example on a machine with TP, I will try to figure it out.
Thanks!
cool cool - let me know if there’s something else I should try here, too…
This problem was addressed in RC3 and should work as expected now.
