It may not be obvious to new users that the missing scores warning is only shown when one of the teams hasn't filled up the spirit scores. It can be clarified to make this clearer.
Some times teams could intentionally fill two entries or it may happen due to network glitches, etc. The TDs should be able to see this easily and be able to talk to the teams if they intentionally filled in duplicate entries (identified from difference in entries). Also, could look at the difference in the full rows - including columns which are not scores related.
The total scores could be confusing when scores for some games are missing from the data. It may be better to move the average columns before the total columns.
Also, clarify that the difference is the difference of averages, not totals.
The self scores don't contribute to the ranking, but we do show a comparison of the averages. Ideally, we want to have as many games as possible included in the calculating the rankings.
It might be nice to be able to link to the spreadsheet row from where the data is being pulled. It would be useful to the Spirit Directors in case of discrepancies that need to be cross checked (like duplicate entries, etc). But, that would expose the URL of the doc, which we don't want during the tournament duration. May be just specify the row/column number instead of linking?
