I have uploaded an expanded example sheet. The link is below (though i think the original link in the first post will also take you to the bigger example.

The new workbook has a data tab for day 1, a table for day 1 and then a data tab for day 2 to show the progress through each update. I have included a tab with an explanation and details of all updates that are being made. This is about the closest thing i can provide to actually being the sheet i use (for data protection i can't show you the original, and besides, it's a 120mb behemoth).

Any more questions let me know, I will start to work on my own code at some point tomorrow and i'll share it as i go.
