Soil improvement using PVD

Question

I want to ask when reviewing soil improvement using PVD, why is the result of the decrease in time using my plaxis 2D when 2 m spacing is faster than 1.5 m spacing and 1.5 m spacing is faster than 1 m spacing?shouldn't pvd spaced closer should be faster? is there any effect on the mesh?

Dear Randy, 
 As I mentioned in my previous message, without any data on how things have been modelled the results may or may not be correct and may or may not make sense. I would suggest you send a service request with your project to https://apps.bentley.com/srmanager/ProductSupport so that one of our support engineers can have a look at it. 
 With kind regards, 
 Dennis Waterman
