I going back to my old system of not backing horses drawn wide.
Anyone else agree?

I know stats will show horses can win from out wide but finding the one horse who gets a good run from the 5 who draw wide is a guessing game

I don't think it can be that simple Wily.

You have to take into account the length of the race and also where the start is, ie is there 800m to the first bend or do they jump straight onto a bend.

I also take into account the racing pattern of the horse, does it lead anyway and will cross? is it a back marker and drop straight out thus negating the barrier draw.

I guess all this points out is there can't be any hard and fast rules  :unsu

Only a fool would argue against the proposition that barriers are important in determining the outcomes of races.

As GT has said there are a stack of caveats that must be considered, e.g. the distance, the starting point at the track in question, and the condition of the track, the field size, the rail position.

Lots of sites, publications, etc, put up barrier stats.  But in the main they're not worth the space they occupy (because they don't deal with the points above).

The size of the field is typically not taken into account.  I mean, barrier 10 obviously can't win if it's not occupied.  It's a mammoth exercise though, to produce tables that DO mean something.

A reasonable simple statistic that can now be calculated with the aid of a computer is the performance of the inside half of the stalls relative to the outside half.

Say it's a 10 horse race at the 1810 at EF ...total the finishing positions of the horses drawn 1-5, and compare it with that of the horses drawn 6-10.  If the barriers have no influence, the scores should be approximately equal at around 27.

Over time you'll then build up a profile for the particularly starting point (by adding up the inside totals and outside totals).  No problems with odd-numbered field sizes (e.g. 11).  You either toss them out - it won't alter the end result - or put half the score to both sides.

You might end up over time for the 1810 at EF with a score of 55 vs 45.  It's then up to you to dedcide on the significance of the difference.

Definitely worth doing if someone has the results, and computer skills.

On stuff I've done years ago, you'll be surprised at the results with big fields at the majority of barrier starts in Brisbane.  The outside barriers are nowhere near the problem that most of us believe.

whether a barrier is significant or not depends on the horse and the other horses in the race more than the barrier itself.

For example my best bet last sat was a horse draw wide at the 1200m at the Gold Coast. Normally a bad move but I knew it had enough early toe to cross easily. Lead comfortably after 200 and bolted in.

Do you then rule out a horse with no speed drawn wide in a race you think will be truely run?

not as simple as just saying wider than 7 never bet.

also a big point in favour of backing horses drawn wide in the right type of race is you will invariably be getting significant overs to it's true price. ;)

as shown by bundy's stats

I tend to operate on a slightly different theory, that is I find back markers from wide barriers to be, if not a plus, then at least not a negative, whereas back markers from inside barriers I find to be a big negative.  I find that backmarkers need space and time to warm up, and that is easier to do when already out wide, rather than trying to find room, which beats lots of good get back horses.

All good points fellas.
I certainly agree that it makes no difference to a backmarker and there are those that hate racing inside others but it takes a heap of time or study to suss all of that out.

I remember putting a line through Brew in the melbourne cup, he drew 21 but found the fence after 100M :mad:

The horses drawn 2 places inside him were 3 & 4 wide for the trip..........pure luck on the day figuring which widely drawn horse will get the run.

I backed Mr Aristos yesterday after cleaning up on him the start before where he drew barrier 4, from memory. he box seated that day and killed them.

Yesterday he drew wide and had to settle 10 lengths off the lead and had no hope. I convinced myself that barriers don't matter and lost a bundle on him. The barrier certainly did matter.  :mad:

Ditto Atapi in NZ. Big field, wide marble he had to got back to last. From 4 he would have possied up mid field and won

The other consideration is the quality and experience of the jock.

DD - you forgot along with rail position, the track bias that can occur cause of it  ;)

Shows how much I bet there, can't back a winner with that pain in the arse voice of Jim Jakes calling.
