So noted.

It will depend a lot on the project, and "where" in the project you are.

For example, for most end developers, the "push" is likely going to be a 
few commits (say, a days work). Probably on the order of a few tens to 
maybe a few hundred objects. It's actually hard to create a pack with less 
than ten objects if you have a few directory levels (a single small commit 
in the kernel is usually 5-7 objects: commit + 2-3 levels of directory + a 
couple of blobs).

For me, as I pull a big merge and push it out, a push can easily be in the 
thousands of objects, just because I merged other peoples combined work 
over several weeks.

And for a "mirror" server, it will depend on the granularity of the 
mirroring.

I think 100 is a nice round number for humans. Worth trying.
