Chief Delphi - Real-Time Scoring Not Working?

I disagree.

The rack was scored manually, that was fine.

The minibot tower sensors were quite bad in the first two weeks of gameplay. The initial fix was to heavily filter the data, which then changed the required time to hit the trigger (which, not being specified as a requirement in the manual, left many teams unable to trigger it because it didn't trigger as specified). A later fix was to redesign the sensors, and this helped somewhat.

However, the sensors still only had a ~95% success rate (based on our 2011 CMP scouting data), and the rules and team updates specifically prohibited the refs from awarding any points to a team which clearly hit the top of the tower. Basically, FIRST said numerous times that the sensors were infallible and there was no room for argument. FIM refs routinely ignored this and awarded some points anyway, but at CMP we recorded several incorrectly scored matches, some of which were close enough to possibly swing the results.

The problem in 2011 was not that the sensors weren't perfect (they eventually got quite good), but rather that the rules and team updates repeatedly asserted that the sensors were perfect and it was not possible to argue any other way.

2010 also had it's faults, specifically when two balls would go through the sensors together and it would read them as a single ball. Offsetting the sensors would have solved this. In addition, they would also give penalties based on a return timer, and an incorrectly detected ball on the return track could force the system to repeatedly give penalties until the end of the match.

I can't think of too many issues with the 2012 automated scoring.
I can't think of any issues with manual scoring. The realtime score is reasonably correct (not off by hundreds of points), and the final match score is always correct (after manually counting game pieces).
