Almost never.  I would only run a re-index for newer versions (such as 
6.5.2 to 7.2) that have a required feature or schema changes such as 
changing the type of an existing field (int to string for example).  Not 
sure what you mean by 'every delta', but I would assume you just mean 
new data?  If so, then re-indexing is not necessary.
