Curious if the audience display and the underlying calculator of team ranking is publicly available. Thx
As of current time, FIRST Engineering has not released any parts of the 2018 scoring system to the public. You may want to try to contact them directly via the above link and include your contact information in there, with a description of what you want and why, and you may hear back.
They actually have the 2018 Off-Season FMS released already.
