Dianetics is Precision run.
"There is no permissive R3R. Skipping R3R commands or not making the PC do each one is giving you keyouts like recalls and self-auditing PCs. The PC is made to execute each step by order even if he's done it. PCs will come back under auditor control!" LRH
A "fast" PC is never too fast for a precision auditor. There is a difference between a fast PC and a PC whom the auditor is not controlling.
R3R is run muzzled. Only the commands as given in BTB 6 May 1969R Issue IR, revised 10 June 1974. "Routine 3R Revised Engram Running By Chains" are used. The full extent of TR 0 to 4 is used. No step is skipped ever.
R3R is precise and exact and never varied whether run by a Dianetic Auditor with no other Classification or by a Dianetic Auditor who is also a highly classed Scientology Auditor.
