In running R3R when the pc’s TA is rising after 2 runs through, the indication is that there is an earlier incident (or in rare cases, an earlier beginning).
One does not need to ask Erasing – solid? when he sees the TA rise as obviously it (the incident) is going more solid. It is correct, the auditor seeing the TA rise, simply to ask for an earlier incident and if “No” then an Earlier beginning.
The exception is the low TA (below 2.0). If the TA is let us say at 1.6 and rises to 1.8 during or after the second run through, the incident may well be erasing as a below 2.0 is abnormal. It will come above 2.0 only when the chain is erased. So one does ask for Erasing – solid? and carries on as usual with R3R when the TA is below 2 but rises.
