Question for anyone knowledgeable with cavity filters:

 

When connecting two band-pass cavity filters for FM broadcast in series such as Telewave TWPC-1005-1 filters, is there a formula to determine the optimum coax jumper length between the two filters?

 

We have a large number of surplus filters and an analyzer to tune them, but noticed the shape of the band-pass varies widely with various coax jumper lengths between the two filters.
