I can see both sides of this issue and I wrestled with this very topic myself. I agree with DG Hustles that everyone likes transparency...including me. However, I can tell you from personal experience that transparency can sometimes be detrimental to our sport because of a few bad apples. For some strange reason, many pool players believe that neither the pool room nor the TD should profit one dime and ALL proceeds should go to the players.
I read a thread once where a TD announced a $100 entry fee tournament, no money added, with a max of 64 players. When the payouts were added up, it totaled $6,000. In this case, the TD was retaining $400 while the room was allowing uninhibited access to the pool tables all weekend in exchange for the "hope" of increased food and beverage sales. Numerous players quickly did the math and jumped on the forum to criticize the TD. They actually expected the TD to travel to the room, pay for a hotel, provide all of the many necessities that a tournament requires, and spend all weekend running it...for nothing. Then, rather than purchasing food and beverage at the room, they wait for a break in the action and go down the street to McDonalds just to save a couple of bucks. Many players actually demand this non-compensation from pool rooms and TDs and will quickly spread their logic (or non-logic in my opinion) to thousands of people instantly over the web. With these unrealistic expectations and demands, in the end, there will be no tournaments...and we all lose.
Believe me when I say that there is nothing lucrative about running pool tournaments! However, in order to prevent chaos started by people who don't have a clue about the various expenses of running a tournament (especially if you are streaming), I believe it is sometimes best to keep that information proprietary and let the history of payouts from a TD speak for itself. No matter what the circumstances, some people will use whatever information you provide to try and bring you down. Just a perspective that I thought I would share.
