Understanding the Data

Why are some of the same models listed twice or multiple times?

The same model is listed twice for one of two reasons. The first is that the Equip Data team occasionally tests the same product sampled from different years to understand how product performance changes over time. The second is that when we engage with a new test lab, the Equip Data team conducts round robin testing (i.e. working with various test labs to test the same product models and compare results to ensure data consistency). The results produced by various test labs through round robin testing are all shared on Equip Data.
