@ITR
Thanks for your response.Let me put it this way How Many bends of the course.If we observe in say HRC the FR star from 1400 and sometimes they are uniform up to WP but sometimes they change the width of FRs at 900 or 550 can we infer that there are 2 bends one around 1400 and one after 900/550.So we need to adjust for both widths for race of 1400&above one for races say 1100 and 1200mtrs.

@ Sun

I have old Fonn's books with race course charts. Every 200 m. are marked on them but most bends start and end at points in between so it is difficult to pin point where it starts and where it ends.

I can send you xerox copies if you provide me a name and postal address. Also, if giving contact details is permissible on this forum.

A careful understanding and interpretation of penetrometer(PNR) can help in picking a winner.

for example race no 123 of Bangalore.

Me Culpa was favorite (Even) and Orenda was second favorite(5/2) in this race. Both were ridden by good jockeys carrying same weight(58.5K). both have recently run 1400m race, MC(54.5K) won(race no32) in 1m 27.81s; while Orenda(55k) was second and clocked 1m 27.63s. Track work was also similar.

How to select the winner?

Me Culpa won by nose - hardridden, when PNR was 4.2, while Orenda was second throughout - well ridden when PNR was 4.8...

It is obvious a runner with almost equal caliber but giving better timings at worse PNR rating should win ; and Orenda won beating the favorite...

@ Chanakyaji and other IRians can some one provide me bend positions at various race courses.Earlier Fonn's book had the plans but I do not have a copy of the book.
Thanks.

@Game Changer
Let me add my views on the subject.Along with Chanakyaji Shri SK Sagar has also down extensive study on the subject but the variable factors in the equation to adjust Timing with Penetrometer reading are many eg
1.First we have to adjust the Time Clocked in a race vis a vis the Weights Raised OR Lowered factor because if a Race is Weights Raised the Timings clocked are not representative of the Class.
2.We have to adjust for width of False Rails though it is announced by clubs saying that the starting gates are placed at appropriate position using Rodometer but I observe that there is a variation however small it may be.
3.To adjust for pace of the race which is next to impossible thing.Fortunately for distances up to 1600 Mtrs majority of races are run at reasonable pace.
After doing all the above adjustments you can attempt adjustment for PNR.So it is a complex equation to be solved.Last but not the least the variation of timings with PNR reading is not linear ie for reading from 3 to 4 is not same as 4 to 5.
Having said that we may to resort to empirical factor and observe the accuracy.As a thumb rule for 1600 mtrs for 1CM variation you can take it as 2 secs.For other distances
1000 1.2 Secs 1200 1.4 secs 1400 1.6 secs 1800 2.2 secs 2000 2.4 secs 2200 2.6 secs 2499 3.0 secs
Thanks.

According to theory, if going is fast (less PN reading) horse will run faster and if going is slow (more PN reading) horse will run slower.

That is generally correct but going affects different horses differently. On Saturday, going at Ascot was good to firm but Cracksman was withdrawn because that going is unsuitable to him. He likes softer going. Similarly mudlarks do well when PN reading is high.

Simple truth is there are no formulas in racing.

Whatever PN reading may be punters will always fail to select winner and will always be in loss

I've written an article in 2008 , reproduced in guest writers column - still available there.

weight of a jockey and PNR are linearly related- provided the jockey 'is on job'- a very complex statement...

Raw timings published by race books - is provided by 'not paid' poor race trackers who mkay or may not go at 5 AM at the race course


bY the way: what benefit/incentive or money - real money : these booksellers ore private tipsters pay to these 'unknowns...'

Dear Rakesh/Krish - Thanks

@ Game Changer,

Adjustment of timing with penetrometer readings is just a waste of time. As per my understanding, higher the value of PN reading is slower the timing. If you are still interested? you do research yourself. Take any race track & race day, record the PN reading then take average reading of timings of either 1000m or 1200m race and record it . Wait for another day do the same. Once you get atleast 3 readings, plot a graph between PN reading with timings. You will find fraction of time difference with respect to PN reading.

Good luck in your research project.

First its unknown that how much minimum difference of penetro meter reading effects horse slowing..what I mean is if reading is at 3.2 and reading at 3.4 ..this .2 difference will make any effect on horse running g...its common sense that the if difference is substantial then it will effect. what I mean if reading is 3.2 and 4.0 then this .8 and more will effect horse running...
