Pardon my ignorance here. Just trying to learn, and am interested in this...

How can it be that you are not changing the checksum when you change other values. I thought maybe if the multiple changes were symmetric they might offset and the checksum would remain unchanged, but that does not appear to be the case with the new temperatures you chose. What obvious feature am I not understanding? Thanks.
