Is the tolerance just slightly off? We can run for more iterations to make the value converge better.

[ArnoStrouwen]

1 vs 1.4 ; 0.3 vs 0.4 I would not call slightly. You can see it in the output.

What about with 10_000_000 trajectories?

oh that's weird. Just on windows?

[ArnoStrouwen]

Yes, not on linux, did not test mac.
