Two things:
1) If the value is greater than somewhere in the range of 78-104 (1 1/2 to 2 years) I wouldn't bother showing it or give it another color meaning it's too far ahead to be anywhere near accurate.
2) Where are you getting the date from on this site and would you mind making your spreadsheets available? I love making spreadsheets and tried making my own based on similar information but haven't found a good way to get the data off this site and haven't had time to put it all together. I saw your similar one based on the Wii and liked the idea of that one too and just wanted to play with a few things myself.
