Dehere, I\'m glad you jumped in, since I know you use pace products. Comments on the RS so far?

did you see the stat 6f sprint no maidens, no wet tracks.

Quirin speed points aren\'t an effort to use fractions to determine who the speed might be. They are an effort to examine running styles. The idea is that horses tend to run as fast as they have to early in the race in order to get the position they prefer. So if the horse gets the lead often, that is telling you something about his chances of getting the lead today (and so on). There is some truth to it. Most pace analysts (myself included) think in both terms. IMO, the key is to get the fractional analysis correct the way you are. The rest is more subjective and depends on the makeup of the field. If you\'d like some input on a speed points rating that you can add to your product at a later date let me know.

dehere

High Roller - nope, missed that one but it seems kinda reminiscent of HRC trying to find a winning formula. Unfortunately, I guess your limitations rules out California, Keeneland, Turfway, Woodbine, Arlington, Presque Isle. In the interest of fairness, I\'ll take a look somewhere to see whether the summary holds up under the guidelines suggested.  

JB - do you look at the Raceshapes as being limited to certain races/conditions?

To answer your question, the first time I used the product I found it to be extremely telling about how the race would \"shape up\". I have not really utilized it enough to have much feel for it though at this point.

fkach

It\'s not my job to defend Race Shapes, but even though the Quiren Speed Points are valuable they are not the whole answer.

Let me ask you a question.

Who do you think will get the lead between 2 horses with 8 Quiren Speed Points?

A. The horse that typically runs 22 flat and recently ran a 21.3

B. The horse that typically runs 22.2 and whose best is 22.1

The answer is obvious when you have good fractional information to work with and not so obvious when you just have speed points. Using Race Shapes does not mean you can\'t also look at speed points and vice versa.

TGJB

Dehere-- I don\'t really know yet about race types and conditions, but from what little I\'ve seen the dirt sprints are rock solid, the grass routes more tactical and thus less predictable.

Fkach,

I don\'t think that it\'s any great revelation that a horse with certain Quirin speed points will be 1st, 2nd or 3rd at the pace call.You need Quirin points to know that? No axe here, but compared to pace data available today,Quirin points are rather light weight.

On the other hand, if a track is playing giant inside speed I would find it of value to know that the rail horse is consistently 22 flat(adjusted) to the quarter and thats tops in the race by even a fifth or two.

High Roller - I stand corrected. I did not have time to go through a complete study as the database isn\'t really conducive to seeing who is w/i top 3 (it is directed more towards beaten lengths data), but I did take a a look at LRL since January 1st under the criteria you established. Of 39 starters with 8 QP, 37 (95%) were within top 3 at first call.

That result was based on 1,399 starters. With an average field size of say 8 horses, that means that there were some 175 races. So, there was a horse with 8 QP once in every 4.5 races. Thus, finding that 8 QP horse is great for 22% of the non-maiden dirt sprints on a fast track, but what do we do the other 78% of the time?

Anyway, I agree that QP is fine for projecting how a specific horse may run in a particular race, but QP does little to predict how other horses may perform in a particular race and what the overall shape of the race may be.

We pace players often also look at the number of horses in a race that have 5 or more QP. With 3 such horses there is an indication that the race may lead to a speed dual. With only one horse above 5 QP and particularly when that horse has 8 QP perhaps we have lone speed. I have yet to do this, but it will be interesting to see how the Race Shapes looks for those kind of races.

Jerry  Used the race shapes and TG #\'s for Churchill and Belmont on Sat. and Sunday. Used just race shapes and Form for Monmouth both days also. Excellent return and data was useful and form full-filling. Understanding the speed pacing depending on how a track is running can be very valuable. Suggest looking at Monmouth over the last two days.  On a another subject I love all the complaining about Poly/dirt handicapping. I\'m not there yet but it give the good handicapper the same chance the Sheets and TG gave people 20 years + over the conventional Telegraph/Form handicappers. Thanks for your continued search for tools to help the handicapper cash flow his habit.By the way Chuckles \"Thoughts to start a weekend\" comment will be exposed in the racing form in the next 6 weeks. I promise to remind him when it happens.  My comments on the race shapes are based on a very small sample

Miff,

My point is that running styles (which is what Quiren Points are actually getting at) and actual early speed (fractional times and Race Shapes) are really two different factors. There just happens to be a huge overlap because very fast horses tend to wind up on the lead and horses that like the lead tend to run as fast as they have to (or can) to get it.

If one horse has been running faster fractions lately because he\'s been stalking some real speed demons, he\'s liable to sit off the pace of a horse that loves to go to the lead even if that other horse has been running slower fractions lately. It depends on whether stalking is his preferred position or the slower horse is capable of running faster to get the lead if he has to. That\'s a running style issue that might best be determined by analyzing past running positions.

If two horses both love the lead, but one of them is clearly much faster, then the fractions will tell you what the running style information will not. It will tell you who is likely to outrun the other when they both try for the lead.  

I have been using both in combination for decades, just never in a formula like Quiren speed points. I use subjective analysis that I believe is far superior to any formula to determine running style preferences and how I believe the race will develop. What Jerry is offering is very valuable from the opposite direction of Quiren Speed Points. It may just take some time for customers that are not familar with pace handicapping to find applications of the information and to realize the value. As a big advocate of pace handicapping with a real lot of experience using this kind of data, it gets a thumb up from me.

high roller

hi, why don\'t you do a simple test and take the top horse in jerry\'s race shapes for 100 races and see what percentage it is 1st, 2nd or 3rd at the first pace call?

HR - sorry, I don\'t have that sort of information in a database. However, for the heck of it I have done a more extended study of QP results as somewhat of a starting point for comparison. Basically, I have looked at every sprint race run on fast tracks anywhere in the country since the first of the year. I got a total of 6,446 such races. Then I looked at the relationship between Quirin points and those horses that were within 1 length of the lead at the first call. The results of that study were:

QP8 = 902 races (14% of all races) had a horse that had 8 QP. Of those 902 horses, 624 (69%) were within 1 length of the lead at the first call.

QP7 = 50% of races had a horse with 7 QP and 59% were w/i 1 length at 1st call
QP6 = 53% of races had a horse with 6 QP and 50% were w/i 1 length at 1st call
QP5 = 70% of races had a horse with 5 QP and 44% were w/i 1 length at 1st call
QP4 = 59% of races had a horse with 4 QP and 33% were w/i 1 length at 1st call
QP3 = 75% of races had a horse with 3 QP and 29% were w/i 1 length at 1st call
QP2 = 64% of races had a horse with 2 QP and 19% were w/i 1 length at 1st call
QP1 = 53% of races had a horse with 1 QP and 13% were w/i 1 length at 1st call

TGJB

HR-- if you were going to do a straight comparison, you would have to take whoever we had as the leader and whoever Quirin had with the most points, whether it was 8 or less.

I planned on using them this weekend. I needed some time off after Derby Week. I will use them at some of the smaller tracks and look forward to seeing how they play out.

MonmouthGuy

I used them at Monmouth on Saturday, and the Race Shapes held up pretty good, even helping me hit one bomb in the 4th, where Little Cherokee was well over a full second faster than the rest of the field to the first call (and closer than two seconds faster than the two favorites).  Sure enough, Little Cherokee was over 2 lengths in front at the 1/4 mark and 5 lengths clear of the 2 top TG fig horses in the 6F claimer.  Monmouth was souped up for opening weekend, and Little Cherokee held on comfortably at 15-1 keying a $140 exacta over the second choice (most likely winner).
