With the figure given in Ron's show, it can be calculated that Channel 4 reckon the total amount won before today was £9,992,179.89

This could give us a clue about the monetary value of the holiday the other week (although we have no idea whether they are counting various things such as the untransmitted game, any bonuses give to contestants and the infamous LTL-match of PJ's game)

Exactly, there have been so many extras given away and stuff that it makes it almost impossible to calculate a total that everyone will agree on.

Dave's spreadsheet, with recent games since he last updated it added in, gives a total of £10,013,967.89 - very close to the amount quoted on the show. But that gives no value to the non-cash prizes or Amanda's game, so he's probably included some "extras" that they have missed out.
