Horse racing draw advantage bias.
There are only 7 seasons results shown here
.
The reason for showing only 7 years results is that until the distance of these races was increased by 26 yards to 7F 26yds in 2000, the pattern showed much less in the way of an advantage during the 3 years 1997 - 1999.
Why the addition of only 26 yards should cause a high percentage of races to be won from stalls 1 to 6 is a mystery, if indeed that is the reason for this current trend.
Whatever the cause, the 2005 season proved this pattern to some extent.
On all types of going, 8 of 10 races were won from stalls 1 to 4.
One result 3 of 8, had only 7 runners.
Please bear in mind that 7F is a long distance in draw advantage terms, over which to expect results to be consistent and reliable.
Usually, as distance increases, draw advantages become less effective.
All this could of course be just coincidence.
It will be interesting to see what happens over the next 2 or 3 seasons.

On good or better going, the Bottom half, Top half split shown at the bottom of the chart favours the Bottom half of the draw by 27 wins to 16.
3 other winners were drawn dead centre.
In 2006, the Top half of the draw won 8 of 12 races.
The Bottom half won 3 races, and 1 other winner was dead centre.

On good or better going, stalls 1 to 6 won 29 of 46 races 63%.
On good or better going in races of 8 - 13 runners,
stalls 1 - 6 won 21 of 25 races 84%.
In 2006, stalls 1 to 6 won 5 of 7 races under those conditions.

Above 13 runners, results spread away from the Bottom 6 stalls.

It could be argued that there are spreads of results in races of 8, 9, and possibly 13 runners, which leaves us with a cluster of wins from stalls 1 to 6 in races of 10 to 12 runners, a very narrow section of this chart.
7F is a long distance for results to prove reliable in the long term, and with so few runners, wins from Low stalls could easily be coincidence.
Note again that the Top half of the draw won 8 of 12 races in 2006.
In races of 8 to 13 runners, the Top half won 5 of 7 races, but 5 of those winners started from stalls 1 to 6.

On good/good to soft in places or softer going, there appeared to be the start of a similar pattern, but 2 winners drawn 7-9 and 10-11 in 2006 may be adding to a spread of wins in the long term.
Overall, stalls 1 - 6 won 13 of 20 races 65%.
In races of 17 or more runners, results spread to higher stalls.
The advice remains unaltered from previous seasons :-
As a general rule, results on this type of going often prove to be unreliable.
There is no recommendation on this type of going.
