Ref:
The correct definition of INSTANT READ is THAT REACTION OF THE NEEDLE WHICH OCCURS AT THE PRECISE END OF ANY MAJOR THOUGHT VOICED BY THE AUDITOR.
All definitions which state it is fractions of seconds after the question is asked, are cancelled.
Thus an instant read which occurs when the auditor assesses an item or calls a question is valid and would be taken up and latent reads, which occur fractions of seconds after the major thought, are ignored.
Additionally, when looking for reads while clearing commands or when the preclear is originating items, the auditor must note only those reads which occur at the exact moment the pc ends his statement of the item or command.
