--stats flag does not count properly

[mgutt]

I mounted an external SMB share as a local path and synced this path through rsync with verbose and stats flags as follows:

rsync -av --stats "${source_path}" "${backup_path}"

Then rsync returned this error:

rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1189) [sender=3.1.3]

So I checked the verbose output and found a permission problem:

DESKTOP-I0HHMD9_Downloads/FileBot_4.9.0_x64.msi
DESKTOP-I0HHMD9_Downloads/FileBot_4.9.1_x64.msi
DESKTOP-I0HHMD9_Downloads/FileZilla_Pro_3.49.2_win64-setup.exe
DESKTOP-I0HHMD9_Downloads/FileZilla_Pro_3.50.0_win64-setup.exe
rsync: send_files failed to open "/mnt/disks/DESKTOP-I0HHMD9_Downloads/FileZilla_Pro_3.51.0_win64-setup.exe": Permission denied (13)
DESKTOP-I0HHMD9_Downloads/FilmeMKVsortbyAudioLastFile.txt
DESKTOP-I0HHMD9_Downloads/Firefox Installer.exe
DESKTOP-I0HHMD9_Downloads/Firefox Setup 82.0.2.exe

I checked my destination path and yes, the file is missing:

But --stats summary says, that all 24,371 files or 22,745 regular files have been created/transferred:

Number of files: 24,371 (reg: 22,745, dir: 1,626)
Number of created files: 24,371 (reg: 22,745, dir: 1,626)
Number of deleted files: 0
Number of regular files transferred: 22,745

What I expect:

Number of files: 24,371 (reg: 22,745, dir: 1,626)
Number of created files: 24,370 (reg: 22,744, dir: 1,626)
Number of deleted files: 0
Number of regular files transferred: 22,744

Because the sender couldn't open the file, it didn't make it into the file list, so it was not counted at all. So, all those numbers are correct, there's just no mention of "Unreadable files: 1" in the stats at this time.

But why are they mentioned under "created" although they aren'T?

As another example. A friend had a defective RAID1 and some files were sucessfully transfered, but many of them not. Example:

Files in source:

find /mnt/nvme0n1p1 -type f | wc -l
9137

Files in destination:

find /mnt/disk2/nvme0n1p1_backup -type f | wc -l
4646

rsync stats:

Number of files: 9,377 (reg: 9,137, dir: 240)
Number of created files: 9,377 (reg: 9,137, dir: 240)

1.) rsync did not "create" 9377 files (maybe, if you count the created tmp files which were delete afterwards, but should be in a different line I think) 2.) rsync did not "transfer" 13628 files (maybe, if this contains retries, but then this should be in a different line I think)
