Have been following your "stats" method from another post without the 92% factor.A couple of races I have followed produced the following results.
27/4/02
BR2/2 Paralo 2nd $1.50
BR5/6 unplaced
BR6/5 I,m in Heaven 3rd $2.00
BR7/3 Lord Essex 1st $6.80/$2.20.

28/4/02
SC4/4 3rd $1.90
SC5/3 2nd $1.30
SC7/5 1st $4.70/$1.60.
Encouraging results so far.Most place systems seem to pick mostly favourites.
With your system, Mr Magic's system and another system I have, the trifecta was picked in BR7 on Saturday.All three systems are based around Average Prizemoney.
However I only pick for a place.
