System Restore set to default size of 15% of drive space. List ShadowStorage
shows 15.7GB used of 16.8 maximum space available, so a quick calculation
shows an average point is just under 1GB.

Keep in mind that if the volume approaches less than 15% free space, the
system will actively work to maintain this by reducing alloted space for
non-critical processes. Each point contains not only the system file
shadows, but also those of a user's files. If you have a lot of files, then
the corresponding restore points will be larger.

From your blog:

"Why should a Restore Point be much less than 2GB? Because restore points
ought to be only differences from the current system state, and if not much
is being installed, uninstalled, updated etc. the changes should be
relatively small."

That's not how vss works. It doesn't record only changes, that would be a
differential backup. System Restore is more akin to a "copy" of the system
at a point in time that can be replaced on demand. Each restore point is a
copy unto itself, and is not reliant on any other point, so each would be
expected to be appropriately sized.
