INSTANT RUDIMENT READ
  1. on rudiments, repetitive or fast, the instant read can occur anywhere within the last word of the question or when the thought major has been anticipated by the preclear, and must be taken up by the auditor. This is not a prior read. Preclears poorly in session, being handled by auditors with indifferent TR-l, anticipate the instant read reactively as they are under their own control. Such a read occurs in the body of the last meaningful word in the question. It never occurs latent.
