Okay, well with my weight ratings, I usually end up with a more compact set of ratings than what you have there, so at the end of this post, you'll see I've made some adjustments to my pricing formula to make it suitable for you to use.

Anyway, as it stands now before I know the final track conditions, this is how my ratings have worked out the race:

1 MISS POTENTIAL - 65.5
4 LIEUTENANT - 63.0
5 NICONERO - 63.0
11 CARGO CULT - 63.0
2 CONSULAR - 61.5
10 ROCKFORD BAY - 60.0
7 SAXON - 60.0
6 NOBLE RED - 57.5
8 LORDS A LEAPING - 55.5
9 UMBER - 55.0
12 STORM ATTACK - 53.5
13 MY GIBREEL - 53.5
3 MODEM - 52.0

Now, to price them, I use the following table to help me:

Margins to Points
Top Rated = 100
0.5 behind = 87
1.0 behind = 75
1.5 behind = 64
2.0 behind = 57
2.5 behind = 50
3.0 behind = 45
3.5 behind = 40
4.0 behind = 36
4.5 behind = 32
5.0 behind = 28
5.5 behind = 24
6.0 behind = 20
6.5 behind = 17
7.0 behind = 14
7.5 behind = 12
8.0 behind = 10
8.5 behind = 9
9.0 behind = 8
9.5 behind = 7
10+ behind = 6
11+ behind = 5
12+ behind = 4
13+ behind = 3
15+ behind = 2
20+ behind = 1

Might look complicated, but it's not really. You simply award the top rated horse in the race 100 points, then you use the table to award all the other horses a certain number of points depending on how many kgs behind the top rated horse they are. For example, my ratings have Lieutenant, Niconero & Cargo Cult all 2.5 kgs behind Miss Potential. The table says that = 50 points. Do that for all runners:

1 MISS POTENTIAL - 100 pts
4 LIEUTENANT - 50 pts
5 NICONERO - 50 pts
11 CARGO CULT - 50 pts
2 CONSULAR - 36 pts
10 ROCKFORD BAY - 24 pts
7 SAXON - 24 pts
6 NOBLE RED - 10 pts
8 LORDS A LEAPING - 6 pts
9 UMBER - 6 pts
12 STORM ATTACK - 4 pts
13 MY GIBREEL - 4 pts
3 MODEM - 3 pts

Now, you simply add up all these points and you get 367. Divide 367 by each horse's score, do a little rounding up or down and you've got the prices:

1 MISS POTENTIAL - $3.70
4 LIEUTENANT - $7.30
5 NICONERO - $7.30
11 CARGO CULT - $7.30
2 CONSULAR - $10.20
10 ROCKFORD BAY - $15.30
7 SAXON - $15.30
6 NOBLE RED - $36.70
8 LORDS A LEAPING - $61.20
9 UMBER - $61.20
12 STORM ATTACK - $91.80
13 MY GIBREEL - $91.80
3 MODEM - $122.30

----------------------------------------------------

Here is the adjustment that I've made to my pricing table to make it more compatible with your ratings method.

Top Rated = 100
-1.0 behind = 87
-2.0 behind = 75
-3.0 behind = 64
-4.0 behind = 57
-5.0 behind = 50
-6.0 behind = 45
-7.0 behind = 40
-8.0 behind = 36
-9.0 behind = 32
-10 behind = 28
-11 behind = 24
-12 behind = 20
-13 behind = 17
-14 behind = 14
-15 behind = 12
-16 behind = 10
-17 behind = 9
-18 behind = 8
-19 behind = 7
-20 behind = 6
-22 behind = 5
-24 behind = 4
-26 behind = 3
-30 behind = 2
31+ behind = 1

Using that table with your ratings we get:

1 MISS POTENTIAL - 100 Pts
2 CONSULAR - 12 pts
3 MODEM - 1 pt
4 LIEUTENANT - 40 pts
5 NICONERO - 5 pts
6 NOBLE RED - 7 pts
7 SAXON - 24 pts
8 LORDS A LEAPING - 3 pts
9 UMBER - 32 pts
10 ROCKFORD BAY - 9 pts
11 CARGO CULT - 50 pts
12 STORM ATTACK - 14 pts
13 MY GIBREEL - 1 pt

The total is 298 pts which leaves your prices looking like this:

1 MISS POTENTIAL - $3.00
2 CONSULAR - $24.80
3 MODEM - $298.00
4 LIEUTENANT - $7.50
5 NICONERO - $59.60
6 NOBLE RED - $42.60
7 SAXON - $12.40
8 LORDS A LEAPING - $99.30
9 UMBER - $9.30
10 ROCKFORD BAY - $33.10
11 CARGO CULT - $6.00
12 STORM ATTACK - $21.30
13 MY GIBREEL - $298.00

Hope all of my rambling has helped in some way. If you think my method is too difficult, then you can use that simple method I showed you in an earlier post.

Good luck with it.
