As I remember, the home team will get the 2/3 of playoff game receipts. But when I checked yesterday game, it seems not to be so.
Here is the game attendee info.
Date	                  Opponent	Bleachers	    Lower Tier	Courtside Seats	Luxury Boxes	Total Attendance	Game Type
3/18/2014 	 KyEhALeBHAI 	12000	2775	      471	                         22	             15268	               Quarterfinal
And I set price as below.
Bleachers : 	12000 	(Current Price: $20) 	(Price as of 4/5/2014: $20)
Lower Tier : 	3000 	(Current Price: $55) 	(Price as of 4/5/2014: $55)
Courtside Seats : 	500 	(Current Price: $190) 	(Price as of 4/5/2014: $190)
Luxury Boxes : 	30 	(Current Price: $1500) 	(Price as of 4/5/2014: $1500)
Also, you can get the arena info from 
http://www.buzzerbeater.com/team/57324/arena.aspxThe total game receipts should be 12000*20+2775*55+471*190+22*1500 = 514895
So I should get 514895*2/3 = 343263, But it's not same with below incoming of mine.
Here is the incoming of mine.
