We could do both systems at once, I think the two really cool things about this one is that 1) you don't get ties (1,2,3,5,5,7,7 etc) you get actual results and 2) you don't get bracket *****/results are much more accurate, basically I think it would just produce much more reliable results which helps a lot for the new top x go through system we're using (along with Hugo's rankings).
I don't know if there's anything wrong with it, so yeah if we do try it and it doesn't work then there's no point using it.
