The numbering system is unique at this stadium. Some of the levels are broken up into 2 parts with the same section numbers. The sections that are closer to the field start with row A and proceed alphabetically through the rows. The part of the section that is farther from the field starts with row AA and then BB, CC, etc.

However this will not necessarily always translate into Row FF being 32 rows from the field as the front sections do not all have 26 single lettered rows.
