Depends on what size the time frame is - 2 hour window, 3 hour, etc. On 2 and 3 hours, I used to have it
be twice at least 30 minutes apart. On 4 Hour windows - 3 times at 30 minutes apart. "All Day" appts...4 times at least one hour apart. On accts with no numbers.....tag it and roll on. But after it is all said and done, it all depends on what the CSR tells the subscriber about the expectations we have of them. If they aren't educated (the cust), they will scream, get to the top and you roll anyway when they are home.
