Advanced Method

Challenge says try to use a sort of 'scoring' method of alphabet frequency to find real plain text among the candidates.

I think that measuring e's frequency will not be working because the plain text is too short!

I want to apply 'Index of Coincidence' method, but not now.. 'cause it will be somewhat hard working!

COMING SOON..
