How often do you read from ratings sellers that their ratings 'are not to be used blindly, they are a guide to the likely winner'? Well my thinking is that I already have that. It's the BF market. As we know, the BF market is 100% accurate, i.e. horses @2.0 will win 50% of races. So my thinking is, if you can get ratings that are 100%+ accurate you back/lay the difference. I do know this works. I had it sorted with Adrian Masseys' ratings. I made a few grand in the place lay market. Fantastic, then Massey closed. I've tried lots of ratings since. All to no avail.
I have seen all sorts of equations for converting ratings into odds. I ask myself why? Surely to simply convert the rating into a percentage should be an accurate reflection of the rating. I'll explain further to clear things up. Add the total of the ratings for all the horses in a race. Convert the individual rating to the total for the race to give each horse a percentage chance of winning. Am I being really stupid and missing something?
Nearly all the ratings I have tried come up with ridiculous odds. Has anybody any ideas? Can recommend a rating service?
Thanks.

Hi, I have used horseracebase* for sometime now and find their ratings to be very good especially the top two in each race. Have a look they give you a free trial and it is not expensive if you go with them mention my name the lad that runs it is called Chris.

Spurred on by your comments re Adrian Massey, I've spent the last few weeks downloading a shed load of data from the Betfair Directory Listing Site.

Some of the results are quite eye-opening. I always thought that novices and maidens were good races to lay the favourite. Taking a snapshot of some races between the 01/01/215 and 31/07/2015 tells me otherwise.

Maiden Stakes: Races 230 winning fav % 40.43
Nov H/Cap Hurdle: Races 32 winning fav% 40.63

I'll have to have a seious re-think about the way I approach these races. Altough the sample is very small, If anyone's interested, I've put it here:
