This is an area I want to improve.

You have to use --rejoin so subtree will remember where you left off
last time.  I also always specify a branch name, like this:

git subtree split -P subproj --rejoin --branch=subproj-to-push

I think --rejoin should probably be default but I need to understand the
code better to make sure.

HTH.
