Im aware the 3 in a row will be near impossible but i think thats what adds to it. The back2back has been achieved so you can assume it will be done again so someone will at some stage be going for 3 in a row.

Also even if u only take a far smaller percentage for the prizepool as you do for the back2back one, because of how hard it is it will continue to rise to i expect triple figures making it talked about.

I understand that you dont want to have money sent to a prizepool that is unattainable so why not use a method they have in the big euromillions lottery. Where once it reaches a certain amount there must be a winner. So say you set the limit the prizepool can rise too. Once it reaches that let everyone know on a certain day the person with the combined best 3 finishes in the 3 tournaments of the day will get the whole prizepool or just a percentage of it.
