Note, it could still be useful ;-)
I've been running my yearly branch profiling build on both my main workstation and my server. I post the results from my server publicly (this is updated every night):

If you check out the branch_annotated file, you can see there's still quite a bit that gets it wrong. Some of these is because of bad assumptions by the developer, others is because the code moved around causing new branches to make later annotated branches go the opposite way.
Note, its still slow to download, not only because my internet is 20mbs up, but also because that web server is running on a machine with this profiling still enabled. I'll rebuild the kernel and disable it this weekend.
