What BDR adds

More games create more evidence.

Persistent identity

One player history across approved organizers and connected sites.

Reliability

Show how much verified evidence supports the current rating.

Provisional status

Do not present limited early history as final certainty.

Category evidence

Repeated performance helps reveal where a player consistently belongs.

What we do not claim

No rating can honestly guarantee that sandbagging disappears. BDR creates persistent verified evidence so sustained misclassification becomes harder to maintain.
