The tutor stated they do not understand Hindi, which contradicts the fact that they responded in Hindi. This could be a mistake or a misunderstanding.

  22. No long dead air 0 gaps over 6.0s, 0s total (0% of the session), longest 0s
    Silence is below -35.0dB — a crude measure on a phone microphone, so treat a low count as weak evidence rather than proof the tutor was talking.

Observations judged, but not counted as the lab objecting
  1. The camera holds still Not applicable to a board session
    Not counted: Measured over 183 known-bad and 29 known-good camera sessions (2026-09-21): raised on 87% of the bad and 86% of the good, and the motion distributions are the same shape — median frame difference 25 on the bad set, 27 on the good. No threshold on this number separates them, so it is reported and not counted.
    measured
  2. Exposure is usable Not applicable to a board session
    Not counted: Same two sets: it raised 6 of 183 known-bad and 2 of 29 known-good sessions. Both too few to mean anything, and the brightness distributions overlap almost exactly. The earlier reading that it 'fires more on clean sessions' was two sessions out of twenty-nine — noise, not an inverted rule.
    measured
  3. Understanding of the concept is checked No concept check was conducted.
    The session was terminated without instruction or questions regarding concepts.
    Not counted: Raised on 87% of known-bad and 80% of known-good sessions. The criterion is honest about why in its own `why`: the transcript has no speaker labels, so a real check and a rhetorical 'ok?' are often indistinguishable, and the bar ends up one almost no session clears. Still judged and shown, because reading it beside a recording is how it gets better.
