Hi Randy

Re your average run time per server job = backup time. I would, as you intimated, rather directly query the backupset table in msdb and do a DATEDIFF on the backup_start_date and backup_end_date columns to get the backup run time. You could do this to each server individually or through a CMS distributed query or using powershell to loop through a list of servers and populate a central table. Just some ideas.
