Basic Mark:

The basic mark for each individual is equal to the Deliverable Mark (in percentage) divided by their estimated contribution, up to a maximum of half ($50\%$) of the deliverable mark. For example, if your team's deliverable mark is $68\%$, the basic mark for an individual who contributed $0\%$ is $0$; for an individual who contributed $\approx 25\%$ is $17$ ($25\%$ of $68$) and for an individual who contributed either $50\%$ or $>50\%$ the basic mark is $34$ ($50\%$ of $68$).
