Estimating the Time required to Build Access Paths

Hi,

I am currently working on a system that is very over utilized from both a
performance and disk space perspective.  We are currently purging old data
(delete phase), and then will have to reorganize files. Of course the
system has many to many LFs. 

I have a two hour window nightly from end of batch/backup to when the
system has to be back for the users.

I am looking for any kind of algorithm or formula to help me assess how
long the access path build portion of the re-org will take.

Any ideas?

Al
