I dont take any notice of barrier draws , if anything I would favour wide barrier draws especially in races with 12 runners & less.

If one would like some proof to test the idea of wide barriers.
Target races with 12 & less runners.
Target the top 2 tipster's selections & bet the wider barrier of the 2 horses or
Target the 1st & 2nd TAB or pre-post Favs, betting the wider barrier of the two horses
In fields of 12 & less runners

One will see days where the wider barrier dominates & other days the inside barrier dominates proceedings.
The SR will be almost identical over say 150 winning results, but the wider barrier will pay a slightly larger average divided.
Run the idea over say 150 known results to see for oneself.

What I call a large field is 11+ runners.
I found its SR the strongest in fields of 10-12 runners.
Some of the larger divs were found in 14+ runner fields
If one wanted more spread , I guess one could also include the 3rd horse mentioned (Optional) along with the 4th-7th selections.
Betting the unders compared pre-post to actual TAB.

For speedy bet placement one can use the bet placement matrix , one just punches in the 1-4 numbers then click, if the same amount is being bet on each horse.
On UniTAB pro-bet it takes about 6 secs. to bet 4 numbers.

If one is using staggered amounts it doent take long to calculate ones bets if doing it manually.
It depends how slow one is doing the calculations.
There is usually only 1-2 bets most times, very rearly 4 horses, so how much time does one realy need?

I use a program called Racetext International which does all the calulations for me & sends the bets off to the TAB in about 4 seconds.
It can do this regardless of how many combinations one has e.g. Dutch bet hole field of 15 runners, minus the FAV & place the bet onto your nominated TAB with staggered amounts for each horse, in 4 secs with 100% accuracy.
Its a great punting tool if one is into Dutch betting of Multiple runners , Quinellas, Exactas, Trifectors.
Try doing that manually.
It also can track money movement & pool sizes for each individual horse at any given stage e.g. 1-15 min out from jump time.
With either graphical or digital layout .


Cheers.
