Hey GiE,

I use the CSV files for all my form analsysis and run pretty comprehensive macros across the whole sheet to get a final output sheet that I like to work with. Having said that, I personally use the WFA (weight for age adjusted) figure. Then I sort the values for each race on this column and then do my form analysis based on the horses that fall with 2.5 of the highest rated value for each race. You'll find a fair number of winners falling within this range. Then you do your more comprehensive analysis of BP, jockey, pace, distance etc. As far as I know these values are similar to the Don Scott system of deriving ratings values for horses from previous runs. Much too complex to go into here but they do work well. This is just my way of doing form analysis that might not suit everyone. Hope this helps and good luck finding winners.

My understanding is that the base rating is the rating on the day and the WFA rating allows for natural improvement based on age to todays race. 

So if a horse got a 45 (base rating) rating in February a year ago as a two year old then was racing in January this year it should have natural improvement of around 9 kgs. So if all conditions were the same we expect the horse to get a 54 rating today.

So when assessing todays race it makes sense to use the WFA rating in the horses history without the need to consider natural improvement.

Hope that helps and this information is accurate
