Notes
Errors before selecting a particular correct item in alphanumeric path (trail #2). Only values greater than zero are recorded.
It is possible that the value recorded here is less than the sum of the values in Field 6351 since this field does not count mistakes made on the latest circle when the trail timed-out before it was correctly selected.
