+Please note, if you are using a simulation configuration that modifies the inherent structure of the above MATsim outputs, that will impact your KPI calculation. For example, if you have used the Eqasim Cutter extension ([link](https://github.com/eqasim-org/eqasim-java/blob/develop/docs/cutting.md)), this will increase the number of trips in your `output_trips.xml.gz` file and relabel some to an `outside` mode or activity. This will impact how the KPI is structured and calculated, and you will need to validate the outputs are as you intend.
