Hello Roddy
I found this post when researching other items on NPS so apologies for the delay in responding.
Our company operates in the agricultural space. We have sucessfully developed benchmarks on NPS and other performance metrics in the agricultural retail sector for those retailers selling crop inputs to farmers. We have explored the agricultural equipment market but have not found anyone doing NPS at this stage. We would be most happy to discuss further if you'd like and share what we have learned from the ag retail space.
