Each selection from the range is expressed by two numbers; the first identifies the

When the "Overwrite" setting is selected, the new records overwrite the old ones,

will keep the number of records corresponding to the selected number, only without
overwriting.
TRIGGER POSITION

Default: 0%
This setting indicates the location of the trigger with respect to the selected length of

split on 20% pre-trigger data, and 80% post-trigger data.
