An appeal to the Collective Wisdom:

I've been told that someone, somewhere once did a study of claiming
effectiveness and came up with a set of numbers that indicates how many
times a first claim results in the actual receipt of a missing issue, how
many times a second claim succeeds where the first one failed, etc.  But if
such a study exists I can't seem to find it.  Can anyone either point me
towards that study (or one like it) or share the results of any internal
studies they might have done?

I'm less interested in how long it takes to get results from claiming than I
am in the ultimate effectiveness of the process.

Thanks in advance for any help.  If respondents wish to contact me off-list,
I'll happily summarize for the group.
