If anyone is interested, it's ABCD repeated with a cheeky CBA... at least for the top half

Method for the top half of Beale Cipher;

Mapped all entries onto Spreadsheet, first occurrence in a black box: when a duplicate occurred I used the formula =SUM(Cell) of the original so when entered it would auto-populate

Mapped every relationship between each sequence of 3 using a fuzzy signature, gap signature, direction pattern of 100
Took the top class count trigrams and mapped them into their relationships

Inputted the above letters into the black boxes in the hopes of hitting some form of cluster
discovered the CBAABCDABCD pattern, toggled the pattern for eight hours until the sequence rectified itself, then marked out where the potential errors are.

now I am too lazy to continue the lower half or map out the ciphertext/plaintext, goodnight
