This sampling approach can result in data which looks "spiky". These aren't real peaks and troughs, but simply noise created from our sampling approach. Over the timescale of a year, these bumps even out, creating a balanced estimate of activity. However, as we model at more granular timescales, the sample size gets smaller and the artifical spikes can become more prominent. + +In order to provide activity levels at a monthly level, we would first need to investigate if that timescale is large enough to smooth out any artifical spikes. + ## How are a Trust's peers selected?
