I ran the No.1 idea through my data base some time ago over 10,000 races & the SR was approx 30% at very short prices.

The 1st race of the day of any track 7 days a week had the strongest SR for some reason 36%SR. It showed a small loss of approx -10%

Fav was based on SP .

So I feel it would be a strong idea to leave race one out all together if looking at laying Favs based on those stats.

Cheers.
