Basic Mark:

The basic mark for each individual is equal to the corresponding percentage of the Deliverable Mark according to their estimated contribution. For example, if your team's deliverable mark is $40\%$, the basic mark for an individual who contributed $0\%$ is $0$; for an individual who contributed $25\%$ is $10$ ($25\%$ of $40$); for an individual who contributed either $50\%$ is $20$ ($50\%$ of $40$) and for an individual who contributed $100\%$ is $40$ ($100\%$ of $40$).
