My rule-of-thumb for one-way lists is

 Auto-Delete= Yes,Full-Auto,Delay(8),Max(3)

 Delay(n)= #days in mailing period + 1   (weekly => 7+1 = 8)
 Max(n)= max number of bounces before auto-deletion
 for weekly mailing, a bouncing address will be deleted in 3 weeks

 Rule: The longer Delay(n), the smaller Max(n)

Probe I usually leave at Probe(10) and don't change it unless the list is over
25,000 subscribers.
