(All WIF start with '5')
Are you forgetting about compressed keys? The corresponding WIF for these are 52 characters long and start with L or K.
I made assumptions. This is one assumption I made, is that she didn't use a compressed WIF.
Also, the repeatling pattern alphabetcanary found is most definitely 100% there. It's going one direction in the inner ring and the opposite direction in the outer. So at the very least, the lengths of the even flames do not encode information. The colors still could, but that changes your count..., something to consider.
