I updated to 10.11.3 via App Store, not the Combo Updater. The download took about 3 minutes from that source. Obviously, I don't know how long the Combo would have taken but I suspect that it would have been longer because the Combo is a bigger file. The incremental update file was relatively small.

The 37 minutes refers to downloading the entire installation of El Cap, which I will use to install it on my friend's computer. I re-downloaded the entire 10.11.3 version and trashed the older version: No point in installing 10.11.2 and then waiting to update to 10.11.3. I might as well do the whole shebang in one shot.

I have never updated via the Combo, although many people recommend it. In all the years that I have been doing this, I have never had an issue.
