Please note that in the section of the manual I referenced previously, LSOFT officially proclaims it to be "days", so no wonder it is thought of that way.

Please place an item very high on the priority list to have this documentation error corrected.

Changing the value for Probe(n) in the Auto-Delete= line is the only way to
change it.  The value of n is commonly though of as 'days'.  However this only
applies if your list mails out every day.  What n really represents is the
denominator of a fraction of the list to be probed.  (The numerator is always
1.)  If n=10 then 1/n=1/10 (or 10%) of your list will be included in the passive
probe at the next days mailing.  If you mail every day for 10 days, then the
entire list will have been probed (unless the subscriber list also changes
substantially during that time).  If you only mail once per week however, it
will take 10 weeks to probe the entire list at 10% each time.

Since n is the denominator, higher values of n will result in smaller fractions
of the list being probed.  e.g. n=20 then 1/n=1/20 or 5%.
