Hi,
The LON-CAPA spreadsheet can be used to implement grading schemes
which feature bonus points. The spreadsheet could also be used for
penalty points.
There has been a recent discussion about use of the LON-CAPA
spreadsheet on the lon-capa-users list.
See the threads:

The LON-CAPA spreadsheet is documented in the LON-CAPA Course
Coordination manual.
The concept of turning in an assignment late is not part of the
current LON-CAPA date management scheme which features three dates:
(a) Open Date
(b) Due Date
(c) Answer Date
Once the due date is reached students may not make additional
submissions. As things stand today, assigning a penalty for late
assignments can be done in a number of ways, with varying amounts of
automation.
For the maximum degree of automation the spreadsheet would be used,
and students would need to be informed about the existence of an
additional "expected due" date, which would fall before the due date
advertised on the Course Contents screen.
After the "expected due" date full points would no longer be earned
for a correct submission made between then and the due date. The
calculation of points earned in the spreadsheet would then involve
retrieval of the date/time of the student's last submission, and a
comparison with the due date/time for the problem.
An alternative, which would require manual intervention by the
instructor, would be to identify which students still needed to make
submissions after the current due date, and then set a new due date,
and problem weight (reduced from the standard weight for the
particular problem to incorporate the penalty) for those students.
If there were many such students, it would make sense to create a
group containing those students, and then set the new due date and
weight for the particular assignment for that group. A downside to
changing the weight is that the total points available shown on a
student's "Grades" screen would be lower for students with late
submissions. If a student calculated a percent score by dividing
awarded points by available points that number would be misleading.
