Hi Marius,
  The examples in the documentation (all be it the upstream documentation, but 
I didn’t think we would have diverged much in this area) had it at 0.01 as do 
all the example configs i’ve found whilst googling - I have also tried setting 
it to 1.0 which  had the same out come.

Regards
  Russell
