I've taken a look at
BetFair's web site. They are providing a PDF file made by Timeform for every race - is that where you saw the going conditions?
Unfortunately we have our hands tied: we may (that means are allowed to) only use the silks data that is available through the API, namely:
Age and Weight

Colour type
Dam Bred
Dam Name
DamSire Bred
DamSire Name

Days since last run

Jockey claim
Jockey Name

Owner name
Saddle cloth
Sex type
Silks description

I promise that as soon as any new bit of information appears in the API, I will add it to MF Pro.
