There seems to be a new error in the most recent version of Gradebookplus in calculating averages in cases where there are exceptions.

I am running Moodle 1.8.3 with gradebook Plus 2.17

In cases where there is a category with one assignment grade in it, excepting a student from that assignment does not prevent a zero being averaged in for their average.

Before I upgraded from moodle 1.6 with gradebook plus for that version,this was calculated correctly and I have confirmed on another installation running 1.6 that the identical set of grades for the 1.8.3 installation is averaged differently.

Here is the simple example I used for the test:

Category A A1 A2
Category E E1

If a student is excepted from E1 they still get a zero averaged in for the E category.

Here are the exact same grades incorrectly averaged in 1.8.3 with gradebook plus 2.17
