That's a horrifically imbalanced calculation.
You don't specify the income we get but you mention the general prize pot of £500k. A prize pot that just so happens to be determined in no small part by league position. TV money goes in there, how much of the £500k is TV money? More specifically how much relates to the BBC Scotland TV deal? From memory it's less than £10k per annum per Championship club. Most of the money goes to top league clubs as all the TV money is split in the same way.
The second half is nonsense as well. The equivalent fixture has no bearing on the next one. You can use it as a proxy but suggesting we gained fans by moving the Queens Park game to Friday for TV is just a nonsense.
The BBC Scotland TV deal is marginal at best for Scottish Championship teams.
Edit - Just to reinforce the point, if the BBC Scotland TV deal ceased to exist, the Championship teams would all lose <£10k of income. Not £500k!
