I just don't see how that accomplishes anything. If a nickel rings up at 21 and a tab at 23, you won't know it by TID. The same segment lights up. Sure, you could say "it's between 20 and 23", but where?
My TIDs are divided by 10s into 9 segments (iron is 1-19). I don't have to look at segments, just the number. The Ace has no number to display. Only a segment. You could put any numbers you want in there. It looks like someone is using the XTerra 305 TIDs to match up to the Ace 250.
