I'd suggest putting a debug showing you the three numbers Ansible is using
for item.size_total and item.size_available. As @klingac mentioned, it
could be that the values that ""df -k" reports or uses in it's computation
aren't the exact same ones that Ansible uses.
For instance, using the numbers shown in the sample "df -k" output -
(51466720 - 40038956) / 51466720 - I calculate "22.2% not the 19% that
"df" reports.
