Sources

Scorecards are downloaded from multiple sources. For each of these I keep track of the number of scorecards downloaded, the number of matches involving this source that have discrepancies (although not necessarily caused by this source), and the number of scorecards from this source determined to be incorrect. I also calculate the percentage of mismatched matches the source is involved in that they are to blame for (at least in part).
