Had some time on hand, so did a quick analysis of MBBA teams' arena sizes and attendances revenue this season so far. Please note arena sizes vs revenue (in bracket). The revenue was taken from the highest gate receipts in a single game :
Ampang Stuporsonics - 26,735 seats ($559,717)
Ginakia - 24,245 seats ($534,191)
Arowana - 20,070 seats ($576,035)
KwaiWah - 20,038 seats ($558,088)
Nick of Time - 20,000 seats ($594,159)
The above are the top 5 arenas in the MBBA ie. arena in excess of 20,000 seats. But in terms of single game revenue so far, NOT has the highest.
