So by blind stabbing we got the answer. This let me try to reverse engineer the solution. If it’s what I think it is it’s dumb. Not at all reasonable. Perhaps, if it’s allowed, someone could post the actual solution to see if it matches? As it stands I’d say finding the middle first is the most important. I then compared that to the remaining numerals using the code wheel to get to numbers that match the answer but if correct, that route is not at all logical.
