# How long before Tessary's groundedness classifier starts flagging answers?

Tessary's groundedness classifier starts flagging a call site once its learned reference holds 100 traces, down from the 200 it used to require; the reference still keeps learning after that until it reaches 1,000, the same as before this change.

Before the reference holds those first 100 traces there's nothing to compare a call site's current share of flagged answers against, so nothing is judged yet, and a call site too quiet to reach 100 traces inside the 28-day replay window is never judged at all. Unlike [Tessary's frustration classifier, which used to freeze its reference the moment judging started](/answers/tessary-frustration/how-long-before-the-frustration-classifier-starts-judging), groundedness already kept learning to 1,000 before this change; only the starting point moved, from 200 traces down to 100, so a new project sees its first finding sooner without giving up the accuracy a fuller reference provides.
