When working properly, AutoSave should be creating and saving to an AutoSave folder within the Project folder structure, depending on the loctation of the Scratch Disks - Edit>Preferences>Scratch Disks. For each session, doing a physical Save (Ctrl-s or otherwise) invokes the AutoSave timing function. On aspect that some miss is that if nothing is done, to the Project, AutoSave goes dormant, so that it does not overwrite all other AutoSaves at the timed increments, thus giving you multiple versions of the same exact file.
In your stated instance, you have it set to do 10 AutoSaves @ 10 min. increments. This will yield 10 files incremented from 001 through 010. When file 010 is reached, then AutoSave begins the cycle all over at 001, overwriting it, and following though the cycle again. This means that 001 could well be newer than 010. To see what the actual order is, one needs to change View to Details in Windows Expolorer and then click on Date/Time. This is more important than the 001 - 010 file naming convention. Note that the times may well not be in 10 minute increments. If you went to get coffee and took 15 mins. to get back to editing, there will be a gap in the timing. Leaving PrPro open, while you go and work in PS, or Au, or SB, will also leave a time gap, as nothing was done in PrPro.
As I work, with AutoSave ON, I also do a Save_As, or Save_As_a_Copy, after a particularly involved session, or maybe heavy Keyframing. The difference between these two is that Save_As will first Save (with name specified - usually an incremented number for me), and keep that version in the program for additional editing. Save_As_a_Copy (with name specified - usually an incremented number for me), will place a "copy" in the Project folder, but you are still working with the original (prior to doing Save_As_a_Copy), and not the "copy." Each can be very useful, and the decision on which to use is up to the editor. If you want to continue working on the same Project file, use Save_As. change the name as desired, and keep editing. To do a "snapshot" of a point in time, that will be frozen exactly as is, Save_As_a_Copy is the choice, and you will NOT be working in that "copy." I use each heavily for the slightly different reasons.
Now, if you Open a Project, edit for a bit, and hit Save once, and the AutoSave does NOT initiate after 10 mins. of editing (your setting), something is very wrong.
Note that if you are working on several Projects, you should have an AutoSave folder with files in each Project folder structure.
Hope that this helps and that you do not have a problem with the AutoSave function. It has saved my bacon more than once. [pun intended]
Thank you for your thoroughness! I understood that the files cycle through the numbers, but I worked for an hour of real cuts and the most recent "auto-save" was from over an hour prior. So I think you might be correct, something is wrong and I should look into re-installing the software. I hope that the other aspects you explained such as where to find the files (there should be a recovery folder on the loader splash screen!) and how the files work is exactly what the F1 help and forums were missing. Thank you!

The auto save folder (and hence files) are always in the same folder as the project, regardless of scratch disk settings.

I have not found this to be the case. I can do a manual save, and then 20 seconds later, auto save times in. The two seem to be entirely independant of each other.

Not necessarily. There are editing activities that will prevent an auto save (Import, render, etc.) If you happen to be doing one of those things at the auto save interval, it will be skipped. I've worked for well over an hour with no auto save engaging. (Hence the frequent manual saves upon any segment completion.)
