Be careful when getting a dogs last run time history, there are often discrepancies between RacingPost, SportingLife and TimeForm. We never did find out why.MattP wrote: ↑Fri Apr 16, 2021 9:10 amThanks. I have a spreadsheet (from this forum) that downloads the Betfair Price data and I process this into my own PostgreSQL database.ODPaul82 wrote: ↑Thu Apr 15, 2021 10:50 pmhttps://promo.betfair.com/betfairsp/prices/
Following is a link to about 14-15 months of data up to I believe August of last year where I've split out the course, trap, winner, distance

I've posted elsewhere think it was in the excel area a file downloader that can be modified to do greyhounds
I was looking to produce and maintain my own database with full result details so I could reproduce the same kind of interface that is on Racing Post or Timeform, ultimately with a view to compiling my own ratings. I got as far as scraping the result page URLs off Timeform for the past 18 months but that was from 1 page per day to find them, processing 100 results pages per day I couldn't get around Timeform's server security!
After reading the Greyhound Mystique thread and the Trading Greyhounds thread I am going to look at pulling the data I need on a daily basis,, possibly from Racing Post. I'm a software developer so the tip someone posted about finding the private API is useful as this will be much easier to use than HTML scraping.
The most accurate seemed to be the data on https://www.gbgb.org.uk/racing/results/
Each track uploads their data to that site and I think some sort of reconciliation goes on and as a result the data is far more accurate.
Having said all that, many believe ratings for Dogs outside of A1, A2 and A3 is somewhat misleading because of Track/Trap bias. Some tracks have allot of bumping in Traps 3 and 4 unless ofcourse a dog is very quickly away.
You would be better off analysing the following:
Grade, Track, Trap
Take Yarmouth, Trap 6 has an overall win rate of 9% but if the favourite is in that Trap then it rises to 19%. But if the favourite is running in Trap 4 then its 47.5%
So, doesnt take a genius to work out that there are repeatable patterns depending on the Grade, Track and Trap.
Have fun,
