IW has multipliers of 2.63 for DOM and 2.38 for INT
If EG has the same multipliers, then we will have 357M x 2.63 + 866M x 2.38 = 938M (DOM) + 2061M (INT) = 2999M (WW)
If EG has smaller multipliers, lets assume 2.63--> 2.5 and 2.38 --> 2.2 then we will have
357M x 2.5 + 866M x 2.2 = 892.5M (DOM) + 1905M (INT) = 2797M (WW)
So, if EG wants to beat Avatar, its multipliers will have to be at least 2.5 (DOM) and 2.2 (INT)
