Just a comment but the BAG+VP they are using in the kickoff field photos for the bin loading elevator looks to be different from the motor in the
loading lanes video which looks like an AM planetary (notice the belt pulley ratio also). I bring this up as I am surprised to see the use of vex parts on the field as traditionally the fields custom game specific components often feature AM parts (lots of churro notably). The field was also not functioning at the kickoff.
Purely speculation but considering the point value of the fuel they expect that teams will be able be to score very rapidly. The change of motor might suggest that they have been having issues with overflowing during their testing and have been trying to increase the output of the "serializer" mechanism to compensate for this. In 2013 we occasionally saw a similar issue with overflow towards the end of the season and I wouldn't be surprised if overflow was a common occurrence at a high level this year especially since they mentioned it in the field tour videos.
