When more than one person creates a scorecard for a candidate, it appears that the overall rating from each scorecard is simply added together to create a combined overall rating.
However in some cases you are not always guaranteed that the exact same number of people will have "rated" each candidate, so the overall rating is biased in favour of people who have simply received more scorecard ratings.
It would be great to have the option to have an average overall rating created when scorecards are combined.
