The only way to assign ratings and the value thereof under varying scenarios, is to have a significant database with reliable statistics.

I have just got myself a database and you would be surprised the relative importance of some factors on profit, not strike rate have.
Similarly, you'd be very surprised how relatively insignificant some data is to filter losing bets.

E.G. Barrier position has very little impact on a large sample of data. Now whether you want to filter it to different scenarios, like front runners and distance is another thing, but overall I'm speaking, barriers have a minute impact on success or failure.

Database is the only way to go if you want to take this seriously.

Good Luck.
