That's what I thought, thanks.

Hmm, now we have to see whether I've understood this correctly.  The 
situation, IIUI, is that if a backup is close to being a full backup it will 
bump it right to level 0, but also bumping is used to balance out the 
workload in some way.  No, I don't understand it.  So - would you mind being 
quite specific in what I would need to do?  It sounds as though your method 
would match my needs.

Thanks
