Maybe so that it is a relatively small sample, but it is a "start" point.
The problem after that is to get enough data analysis carried out to be more confident in the IV figures.

A reasonable suggestion to start with. Working out how to extract the different classes from the spreadsheet is the biggest hurdle to overcome.
For instance : SC1MW - BM75 - RB71 - Open etc.
Might be able to do it with a Lookup function but I don't know.
Back to the grindstone I reckon.
