Mike, you may want to recheck some temperatures. The original ";" of "2" is given as [32200]. In the new diagram, the central part is given as [31124] and the outer part as [33214]. So the central part of the diagram is not given the same number as originally assigned to "2". Plus, the TC who creates these messages is very embarrassed. Just as many of you decode the messages without the aid of a calculator or computer, they are created without any such aid, and four of the temperatures listed were incorrectly encoded. Here are the new numbers, which I will put into Message 8 later today...
