Managed to get my own spreadsheet together and have been recording the neurals now since about friday last week. Obviously going to need a LOT more data before the Impact Value's start being representative of the true impact of their variables but at least its a start.

At the moment i'm gauging the impact the race variables have on the neurals to hopefully get a more accurate adjusted version of the neurals. I gave it a try yesterday with the limited data and had some success plus the Adelaide Cup winner became the 4th top rater instead of about 7th or 8th in the neurals.

Race variables im calculating IV's for:
- Distance
- Prizemoney
- Conditions (G,D,S,H)
- Venue (Tatts code's at the moment, with more data will likely move to Metro/Provincal/Country the same as garyf)
- Race Rating
- Race Age restrictions
- Race Sex resitrictions
- No. of Runners

I might start posting some results in another 2-3 weeks time once the data has been given some time to at least build up a little. I still need to get in contact with Feeble though and see if I can do it on some historical data as well. Will post more updates as I go for those interested.
