HPF2 awards points based on the number of structure prediction attempts. In the majority of cases, this will be the same for each result within a workunit. However, there will be a few times where one result will have attempted more structures then other results. In these cases, the result will be granted more credit. Each structure prediction attempt is close to the same difficulty so if a particular result has attempted to do more attempts then it has done more work and thus should get more credit.
