At the release of the Golden Age of Tech in 1996, COB explained to the audience how the answer to each question in the new drills is an excerpt from the exact LRH reference for handling that situation in session.
Therefore, he said, “the drill IS the reference".
In an I.G. Network Bulletin written shortly after, COB elaborated, saying that because the drill is the reference, a student who misses a question does not go and look up the original HCOB “unless he flunks repeatedly".
The concept that a sentence or two, taken from a reference, IS the reference, is brand new.
Under LRH, a flunk, whether on a starrate, spot check, meter check, or drill, always sent the student back to restudy (and word-clear) his materials — not an excerpt from them.
