In running triples after running single flow on several items, it can be difficult if the TA is high at session start.
The correct thing to do when an auditor starts a session to run flows 2 and 3 on a single item already run and finds the pc's TA is high (3.5 up) is to send the pc to Review to have his ruds put in.
The TA may not be high on the 2nd or 3rd flow about to be run at session start but on some other chain.
The rule is simple:
When starting a session to run flows 2 or 3 of a single item previously run in an earlier session, and the TA is high (3.5 up) at session start, send the pc to review for rudiments.
In actual practice one can sometimes muddle through and the TA will come down and the needle F/N on the Flow 2 or 3 anyway. But the auditor will have to be very alert to blowdowns, which indicate a basic has been reached, not overrun it beyond F/N and generally run a flawless session.
