I'm not sure I follow the logic in those ratings Ferdy. How can distance beaten LTO be used to rate a horse running in a different race against different competition?

This was the original thinking behind these ratings, but I have tweaked them so many times. They originally came from a chap called Rainy California who used to post on the Massey forum among other places.
Below is just one of many attempts i had at trying to create a rating for horses.
About 12 years ago i started to build my own ratings for handicaps using a point count for each horse. I wanted to keep it simple and base it on distance won and beaten throughout the different class of races but at the same distance, matched to a distance won or beaten scale for each runner. I only concentrated on sprint races and assumed the average distance covering the field first to last was 15 lengths, then everything was based on the last three performances.
Basically i started by only using 5f and 6f races because they are usually true run races with no hanging about and the distance between first and last was not a great deal. I then took every class of race from group one down to sellers and gave each class a top rating. I used 140 as the benchmark figure for a group one winner equivalent to 10 stones in weight and dropped the points by a descending figure for each length beaten throughout the class of race until arriving at the lowly seller which would of been about 5 stone or so lower, so a horse getting beat 15 lengths or more in a seller would record a lowly 62, to trouble a group one race it would need to improve by 78 points to 140. (5stone 8lb) Well that was the theory anyway.
I devised this system many years ago and was bought by a 'sporting' publication and they sold it in their newsletter each month, referring to it as the 'key' for £49.99....jeez i wish i woulda settled on a percentage cut lol
Once again it is only for 5f and 6f races, and when calculating each score the previous three races must have been over sprint distances otherwise it was not included in calculations. A difficult system but a specialist one.
GROUP ONE
winner by up to 3 or more lengths = 143pts
winner by up to 2 lengths = 142pts
winner by 1 length = 141pts
winner by 1/2, sh hd or nck or nose = 140pts
btn up to 1/2L = 139pts
btn up to 1L = 138.5pts
btn up to 1.5L = 138pts
btn up to 2L = 137.5pts
btn up to 2.5L = 137pts
btn up to 3L = 136.5pts
btn up to 3.5L = 136pts
btn up to 4L = 135.5pts
btn up to 4.5L = 135pts
btn up to 5L = 134.5pts
btn up to 5.5L = 134pts
btn up to 6L = 133.5pts
btn up to 6.5L = 133pts
btn up to 7L = 132.5pts
btn up to 7.5L = 132pts
btn up to 8L = 131.5pts
btn up to 8.5L = 131pts
btn up to 9L = 130.5pts
btn up to 9.5L = 130pts
btn up to 10L =129.5pts
btn up to 10.5 =129pts
btn up to 11L =128.5pts
btn up to 11.5L =128pts
btn up to 12L = 127.5pts
btn up to 12.5L =127pts
btn up to 13L =126.5pts
btn up to 13.5L =126pts
btn up to 14L =125.5pts
btn up to 14.5L =125pts
btn 15L or more =124.5pts
Then onto group two races with the benchmark dropping 7 points to 133 for the shortest of wins etc etc, in my opinion this was the equivilent of getting to within 6.5 lengths of a group one win whilst a three length winner of a group two was equivilent of getting to 3.5l of a group one win. Each table dropped 7pts through the following range and the points dropped by the same half point as given above. Each class group had the following start points and dropped in the same way as the table above.
G1 / 140
G2 / 133
G3 / 126
LISTED / 'A' HCPS / 119
B HCPS / 112
C HCPS / 105
D HCPS / 98
E HCPS /91
F HCPS / 84
G SELLERS / 77
After calculating the last three runs of each horse (using class and distance rating) the figure was divided by three and whichever came out highest was the selection. It certainly threw up some huge priced winners but it was time consuming as every horse had to be rated even in 20 runner handicaps. Throughout the following couple of years it performed very well and dutching the top three rated was giving a healthy profit. I was still working full time and couldnt sustain the time needed on it. I could only get the form from the racing post and todays internet access would make it far easier.
. What i didnt explain in the initial post was that every value is based on a horse carrying nine stones in that race. For every 1lb over you would add a point and for every 1lb less than nine stones you would subtract a point, but it was always from
actualweight carried.
I got the guy who done it a couple of days later (and he was taught an almighty lesson!) but the laptop and all was long gone.

) and it also happens to be the official start date of my new yearly all weather campaign. I've had a pretty steady past year minus the couple of months off over the stolen laptop. I took some time off away after that as the thought of compiling a new database from scratch and having to work without one for the foreseeable was too much. However the new database build has been under way for a few months now and things are slowly starting to take shape again.
