Re: paper: 4536 scouting database BETA

I have just uploaded version 1 of this database. It is populated with all week 1-3 events.

In addition to adding the additional data, the two main changes since the BETA include:
An alternative calculation of eOPR (elimination OPR) is now included for each team. So there are now two eOPR calculations, which I have dubbed eOPR1 and eOPR2. Details on how these are calculated can be found in the "instructions" sheet. Although I have not verified this, I expect eOPR1 to provide better elimination predictions at weaker events where captures are more infrequent, and eOPR2 to provide better elimination predictions at stronger events where captures are more frequent.

A new "world results" sheet has been added, which allows for component comparisons for every team at every event in which they have competed. Be aware that this list will have duplicates for teams that competed at 2+ events. Also, don't compare individual defense crossing data unless you know what you are doing. For example, team 5114 has a drawbridge contribution of 1722968039259170.00. 5114 is not that good at crossing the drawbridge, this just means that the drawbridge was not chosen frequently enough at Midland for there to be meaningful results for drawbridge contributions. As a rule of thumb, you can almost always trust the rock wall, sally port, and cheval de frise contributions, but be wary of the others.



Remember, this project is still quite young, and there are very likely errors in places (especially since I have not yet automated everything, and have to do some copying by hand). If you see any errors, please let me know and I will look into it.
