Hello Burdekin,

in my opinion, you have two different ideas in your post.

1. Your ratings, where you are rating each horse in each race, and
2. A "system", where you put your ratings through a series of filters to produce a bet.

51 bets is nowhere near enough to base a solid judgement on, but it is a start. Monitor it for the next 50-odd bets at least to see how it goes, and then you might be in a position to start making judgements.

I don't like the ratio of 22 wins and 32 places. I would normally expect to see placings to be around twice the wins.

As for the ratings, how do they perform if you were to back every single top rated for the win? 670 races is a reasonable sample here, and I would be seriously monitoring this to see if the basis of any systems you build on them are sounds.

Cheers,
Chris.
