Hi Everyone,

I am relatively new to greyhounds and was exploring stats to find some trend or system. I was looking at trap stats for last 5 years for the top courses. I have used the data from http://www.greyhound-data.com

Now the interesting trend is that in majority and i mean 90% of the courses, Trap 5 has the least win %. The question i have is why is this so? In case of non-runners, is trap 5 left empty??

i have searched everywhere but cant find a reason so hoping that the good people of the forum help me out here

thanks
ocean

Ok wanted to make sure i wasn't been caught in a net.

I don't believe in stats in greyhound racing, some do but i don't. There are many reasons why trap 5s may not have won many races. Every single race is different so there are different reasons for each result. The dog in trap 5 may want rails so he is badly drawn. The dog in 4 may move wide run up so the 5 could struggle for a run early. The dog in 6 may move inwards so the 5 may struggle for a run early. Also the dogs in some races in 5 may be just not good enough.

thanks ReimerpYsatnaf , i was worried if i have missed any obvious reasons but looks like it is just the worst trap for a dog to be in..
would appreciate feedback from forum on the table

I will explain why trap 5 wins the least races generally although trap 4 is the most difficult draw.

Firstly traps 5 and 6 are typically wide seeds in most races which means they have got the furthest trip round
the course so it becomes more important not to get out trapped to the bend as this creates even wider routes for
them.

secondly and most importantly in trap 5 case there is a massive bias towards trap 6 over trap 5 and the reason for this is that as the hare passes the traps because of the dogs angle of view of the hare from there staggered boxes
trap six always sights the hare first and springheels out the box ahead of trap five, from then on five is at a disadvantage round the  early bends.

Trap 4 is still the hardest trap to win from but looking at stats wil not show this, what you have to remember is that the majority of best form dogs in the race are placed in trap 4 to handicap the runner, classily known as the coffin box as they are the meat in the sandwich between the wide runners and 3 inside runners that will try and steal the inside of the intial bend.

I hope this clears the matter up for you and explains the reason for the lower than average strike rate of traps 5 and 4.

To prove the point see if you can get some stats for australian course that typically use an inside hare, yuo will notice that trap 6 or 8 will no longer have its fine strike rate and the inside runners will have the sighting the hare first bias in there favour.

slow Going bias

When the going is slow and the average times are 0.25 plus slower due to rain soaked surface the inside runners that normally can hold a tight arc round bends are unable to do so and also the inside of the bends due to dogs mudding up becomes very sticky, mean while the outside of the bends remains much more sound. This gives the wide runners as much as a second advantage in very heavy going, so in such conditions backing wide runners and laying railers can be very profitable.

fast going bias

When the track is running fast and the average times are 0.25 plus due to track being very dry the inside and middle runners have a big advantage over the wide runners as they have the shortest route in the fastest time and the wide runners have even more trouble trying not to run a wide course as they are running slighty faster than normal

It will be noticed that backing wide runners at many tracks in summer is not profitable and trap 1 is at this time of the year by far the most profitable track.

Interstingly when the track is frozen it can also run as much as half a second faster in these conditions it pays to back early paced runners in traps 1 to traps 4

seasonal performance type bias

This effect is the least known and a real gem, in my research I have noticed nearly all tracks show trends that indicate when the weather is warm in spring to autumn its the stayers that have an advantage over early paced runners apart from tracks that are bias towards early paced types like crayford.

In winter when the weather is much colder the early paced types have an advantage over stayers and can win the majority of races.

Now I have contemplated why should this be, what is the reason for this and the only conclusion I can arrive at is
muscle type, muscle is ether fast twitch (white) or slow twitch(red) , red is more oxygenated and relies on the cardiovascular system to pump oxygen rich blood around it. On the other hand fast twitch relies on stored energy and isn't as reliant on oxygen. When muscles are not warmed up and cold they take longer to receive the oxygen they require, this is the type of muscle that stayer have more of and when tendons are cold they tighten up and favor the fast twitch type while the slow type muscle fibers take longer to warm up, usually in winter when the race is over!

personally I would love to discredit seasonal performance type bias but having looked at thousands of races and seen it occur at nearly all tracks including crayford I now have to contemplate having full years of records to calcualte the massive difference in profit this factor induces, thats why I am now spending time designing betting software angled towards trading as mastering tissue prices for value is a massive undertaking.

By:

When: 25 Nov 11 21:03
ah but does it rain more than its normal or fast as if it does the grading ladder shoves majority bias into its correct grading level, here it is rarely slow so the grading is bias towards normal-fast going , reckon you need heavy going in ireland to see the effect, I know one thing when irish horses come to cheltunum and its heavy going they leave english horses for dead unless they have a bit of irish in themCool

one of my favourite tracks is leopardtown, went through the card at one meeting early this year, class races.

Leopardstown is a great viewing track, the Christmas, Champion Hurdle and the Hennessy meetings are brilliant. Punchestown is a great course too, the festival there is top notch and it's a great place to be when the weather is decent. Naas and Navan are 2 other great National Hunt courses where you need to get every inch of the trip.
Luckily enough i'm only about a 10 minute drive from Leopardstown and the other 3 are easy to get too as well for me.

thanks bf_fanatic for your helpful posts... i have sent you a pm as well

to all others who think its a load of b0ll0x, can you share your thoughts as to why i should not pursue this angle further.. i am trying to get data on odds and once i combine with the trap stats i am hoping that it can point to something meaningful

thanks

it will point to something meaningful.....
but you have to keep your trap shut
because when you come on here you look a bit of a dcik
to the majority of these doggie boys
i'm a stats geek, but i also own and about to start breeding greyhounds
i put the earnings back into the game
the lads on here are die hard doggie boys
if you are gonna crunch numbers its feck all
to do with the animals is it ?
so be prepared to take a bit of stick after all
it is the greyhound forum... not the maths or statistics forum , O K ?

a certain amount of information sharing is beneficial to everyone, isn't that the whole idea and beauty of the internet, I know the internets original job was to create a military command system that would survive having
parts blown away in a nuclear war but the internets current use is far more beneficial to the human race provided we
all stop being greedy and self centered and show far better attributes of human nature.

my last comment probably explains why persons residing in china are unable to have free speech and access to the internet and why I and others believe its this mentality that will prevent china from ever being the number one economy in the world when it cant embrace fairness within its own  culture and political sphere, time will tell but I think there will be a melting point for china at some point, just a question of time and the perpetual advance of human nature.

americans suffer from similar over-control by there goverment as they cant even have a bet online, as usual its the europeans that have to lead the way in culture fairness and lets not forget it started in greece so lets hope they can pull themselves out of there economic problems in this complex economic world we all now live in.

basically if you back trap 5 make sure if an early bird it can beat six to the bend or its a very good tracker/stayer
anything else is at a disadvantage, only marginally but enough to knock an edge off and into loss.

trap 4 is the real bogey trap, jokers to the left and clowns to the right, traps 2 and three may aim for hare and chop at lid rise, traps 1 to 3 can take its inside advantage away and traps 5 and 6 will see hare first, thats why good dogs are placed in trap 4 to handicap them, trap 4 is ok in summer when track is fast and its a stayer or bullet trapper.
