About rating Greyhounds

[DuckandDive]

did you have the first race at Sunderland?

No live show, so used the Timeform betting forecast for comparison, for now.





--

The live market told the story. Ratings held up well though.

Took a look at the Sheffield morning card. Not gonna post up all the racecards, but wanted to produced a simplistic rating based on previous post.

The live odds are from Bet365 (all the others follow them after they post). Betfair gets busy around 4 minutes before the off time.

Currently the staking is Kelly based. (more perceived value bigger bet to a maximum of 2% when compared against my tissue)

Notes:

Trap 2 opened up early doors @3.50 and quickly dropped to 2.38 as I prepared to post in the thread.

Early market makers are setting up Betfair like so.

Weird betting at the off, in that race.

Inputting the Betfair odds 2 minutes before the of. gave me 2 back bets (T3 & T6) and 1 lay bet (T1).

Kevin I'm just testing the sheet at this moment, on todays Sunderland, will just check how it works, I have changed the HCP column to now reflect what the Handicap means in time adjustment, these were two dogs from the 1st race , where do you get your fields and results, also its stale data now from last month

Hello Grant

The data is a combination of 2 sources, until recently all was taken from Timeform, now just some of the data from there, bends, Betfair SP, their ratings and checks on the other.
Greyhound Racing Results, Form & Betting Tips | Timeform
The lengths beaten I convert based on time checks, so say a quarter of a length i might change to an eighth or three/eighths depending on the actual time.
The reason I have some in small letters, (should have chenged them forst!), they now come from GBGB were all the results for Timeform and the likes come from - Greyhound Board of Great Britain

I haven't updated for a few days but can do so and repost if you would like?

so all the times are they actuals or adjusted from the winners time lengths beaten converted to time?

The times are all actual read off the finish strip by the racing manager at the track. I just adjust the beaten distances to eightths instead of quarters. A good way of spotting any errors, of which I have found very few over the last 8 years.

Hi W woof43

Attached results up to yesterday.

Earlier in the thread you were asking about Slingshot Poppy, an impressive winner at the meeting on Friday night, a big Group 1 event and highlight of Sunderland season, The Classic. Semi Finals are on this Friday.

I'm not really 100% confident in the times I'm considering as the Raw actual time, been looking at those two sites, some of the beaten margins are very different between each site and even what is on your sheet, roughly a length can be 1.1mtrs I ran a couple of helper cells to try and match the times up. Good man I will merge the new data and check the fields for this Friday. I did run your HK sheet as well the other night, the same as Mikes, using the speed numbers only had a few good priced winners, but the range between numbers for some runners when referencing the actual form seems to have a few discrepancies anyway ty

Thanks Grant
The handicaps I don't know, lately they have been putting the poor dogs a long way clear. Theie time tends to depend on how long tey can stay away from the pack as they soon down tools when caught! To do a plan by handicap marks I don't know, will have a look at it. I just always used the 0.08 for a metre head start and never thought along your ideas of a different value for a different start.

The Hong Kong figures a few discrepancies? I will send you sheets I use, probably not as advanced at this end!

Have it sorted now, the last few columns are the relevant ones, just redoing all the TV's

This is what I have for Slingshot Poppy, there are some very good dogs racing at the track.

Yes she is very quick early on. There are 3 semifinals tomorrow. Woltermade is an excellent dog as well but that was his first race at Sunderland and likely smarter tomorrow.
