For the official wooden illuminated Tricky, the larger circle should be centered around the Annual Chairman's spot, while the smaller circle should be centered on the Keynote Chairman.
For the MagTricky, if a crown is shown on the image below, the large gold magnet should be used to indicate a consolidated Chairmanship. Otherwise the two smaller silver magnets should be used for each Chairmanship.
