@Pneumonoultramicroscopicsilicovolcanoconiosis –
Given the full Playfair Grid is now in case file 9.5 … the first incorrect part of my plaintext involved the RH IS pairs not giving the ‘correct’ decrypt for a ‘normal’ playfair. I looked into that, and whether there were similar mis-decryptions. That led me to realise something was different and to make a simple change in my playfair program.

@NoESC – Regarding accuracy, like 8B, take the text ‘as-is’ with X’s inserted where necessary for double letters. As a tip, having been enjoying the NCC for a few years now, I submit plaintext without any spaces or punctuation straight from my decryption program output (although I will have read it to check it looks correct). I understand the NCC site checking program removes punctuation anyway. I only add spaces, remove extra X’s etc afterwards once confirmed.

, as usual, I leave to your moderation discretion to assess if this is too much.
