Bernie, you can read about the Composite Speed Rating (CSR), new to RDSS2 (i.e. not in older Sartin programs) in the RDSS Documentation PDF found in the RDSS Documentation section.

Here is the link to the RDSS Documentation PDF, which you can download and read for handy reference:

http://www.rdss2.com/pubs/RDSS2.1.Glossary.pdf

CSR is first mentioned on Page 3 of the Documentation. In the PDF, you can search for Composite Speed Rating or CSR to find other references to this factor.

You can also search the P&C site using the Site Search tool (http://www.sartinmethodology.com/googlesearch) to find existing discussions about CSR and its usage.

Still, I can recommend you talk to Dick M (rmath) about the work he has done with this and other factors. He has done that a lot in other discussion threads.

Ted

Bill,

Just a question. Is the CSR stat shown in your post, the original CSR that you get when you open RDSS or is it the adjusted CSR (if required)?

The reason I ask is when, say, a horse is running today at 9F but its last or second last race was an 11F or 12F race the usually slow adjusted speed rating from the marathon makes the CSR rank vs the other horses so low as to not be in the top 5 CSR. The CSR can also be low if the last or second to last race involved a significant trouble notation, in which case you might want to have the program not use the troubled race.

Regards,

Hi Bill

Lovely weather we are having here in Northern San Diego. If I could I would be building an Ark

Bill What I posted from my model is out of the box RDSS. I am not sure how to adjust the CSR numbers

What I can do is post my SoCal model sorted to eliminate any race longer than 8.5 furlongs. This way in the few instances were a horse had been running marathons, and now is cutting back to 8.5 or less, I don't think the percentages would be much different.

Here is the chart from above but with no races longer than 8.5 furlongs

That is absolutely the case. Part of the race prep process has to (still, of course) be looking very carefully at the horse's record. Using or not using a race line in it's (CSR) computation is crucial. Absolutely crucial. I think Ted and I talked once about being able to select which races to use for this number, in RDSS. I always use adjusted numbers (which come from TrackMaster) in my calculation of this, (and related numbers which in my models go into an entirely separate set of "further" data .. ie further numbers that can flow from just one set of numbers. I calculate my own CSR, but it's virtually the same formula that is in RDSS). They are powerful. I would defer to others who have a lot of data on these, in terms of stats, but in general, TrackMaster's adjusted numbers, with further statistical manipulation, (ie a correctly calculated CSR), are quite powerful. There is a short YouTube presentation of how TM does it's speed ratings, if anyone is interested.

Also just a brief note about the "#num!" (error message) you see in Bill V.'s screen shots. The Excel "min" formula, ... the row with the "blue" 0.85 (which if you're using the actual worksheet Bill is, means that 85 % of the data in that column, falls within the range of "1" to whatever the "min number" is showing as. The "min" is adjustable ... he could change it to 0.50, or 0.75 or whatever he wants to see. That error message means (almost certainly) somewhere down in the column of data (that it is calculating), there is either a blank or a "non-number". If that gets removed or fixed, the field with the "#num!" error message will display an actual calculated number.

Very glad to see the way that data is summarized was useful, Bill ! Thanks.

Happy and blessed holidays to all !!

Tom
