Data Coverage

We're continuously working to improve the data coverage on Bricks by Numbers. The data curation process is quasi-automated; however, it takes time to validate and ensure complete coverage. Complete sets are measured as sets where all part prices are available and included in the BVI calculation.

This page is updated with each site release with the latest data coverage metrics.
