One of the difficulties we have with the data set is that we can't determine what the aggregate sentence is. Although situations like that are rare, it is possible that a number of charges are convicted in the case. I know from the data set generally that three-quarters of all the cases that are convicted have only one conviction in each case. The vast majority are of that type, not the type where there are multiple convictions in the case against the individual.
