Running your script I will get:
press [ Fn + brightness-down ]
Brightness changed to 6
Brightness changed to 5
Brightness changed to 4
Brightness changed to 3
press [ Fn + brightness-down ]
Brightness changed to 2
Brightness changed to 1
Brightness changed to 0
The output of a single key press of [fn + brightness-down] on
/var/log/acpid is:

FWIW, I get the same jumps when I hit "Fn + brightness-up".
[...]
If I call ACPI directly, i.e., execute on the shell as root:
/etc/acpi/
Or
/etc/acpi/
Then the levels will be changed one by one, i.e. 7 -> 6 -> 5 etc.
[...]
If I had "gpmhelper.py" running the brightness level will go from 100%
-> 0%, and from 0% -> 100%.
