Hey Indee, thanks so much for giving it a try. I understand that the manual is a little ambiguous and I'm working on that. The last four pages of the manual tell you how to get A, B, C, and D, while the third page hints at the order they need to be input in. When the manual mentions "examine the delta (difference) between positions 2 and 3," it's referring to the values at the second and third positions of the 4-digit reality code. Essentially, most of these requirements should be directly applied to the reality code. Hope it helps and that you’re willing to give it another chance :)
