Back all Selections / Dutching X% of Book Value

[dkedwards]

I have been experimaenting with Dutching Horse Racing for a while now and have written / copied / amended numerous guardian rule files to cover different scenarios. However, there are a couple of points that I would be grateful if anyone has an answer to please?

1) Am I correct in thinking that if I create a rule to Back All selections, I cannot set a parameter to stake atbest market price. Instead (and unlike backing a single selection) the drop down is shaded and only fixed odds box is available.

2) Also whilst it is possible to back selections greater / less than a given fixed odds value, I would like to back say all selections under the first 75% of book value. Is this possible in Guardian without manually converting the odds to percentages (or vice versa)? I currently have a seperate back rule for every selection (up to 25 runners) and setting a condition to screen out certain odds values (not percentage of book value).

I notice that there is a book percentage condition but I am assuming that this relates to the value of the whole race and not the percentage value of the selections?

Many Thanks

Not sure about 2), but for 1) if you set the odds for 1.01 then it will automatically give you the best market price available.

For 2) you could try a few experimental things in multiple copies of BA like:
a)dutch the 1st 2 if fav is <2.0
b)dutch 1st 3 if fav <3.0
c)dutch 1st 4 if fav >3.0 and <4.0
c)dutch all runners priced under 10 if fav >4.0

You should be able to find something that comes near to 75% plus or minus a few percent with a bit of tweaking.

Thanks Dublin Flyer. I'll give these an experiment. Always seems obvious when a fresh pair of eyes looks at it!
