Assignment

I would be interested in the answer to the above as it maks me feel nervous that I do not know what and why the database is doing something...

BUT
NOW A QUESTION...

9000 as a default is ... strange.... guess I typed this in when I set up Moodle by accident.
Can I change this now (we already have 9 months of course data ( .... sections/assignments) in the database.
Set it back to 100? The normal default?
Or will this break the database and the values already in?
aka does it rescale all grade points?

If Moodle/Database has some weird iteractions because of that 9000 this might fix it.
BUT
if anyone can answer the issue of the original problem it would ease my mind

Again. Thanks in advance
Steve
