All set. I'll send you the xls tonight.

Greatly appreciated SB, i'll go back through race by race tonight as well and place the race data into my recording spreadsheet.

I'm at a bit of a crossroads as to if I should refine the selection criteria further or leave as is. The reason being is that currently the ratings/overlays approach is having a bet in 1 of every 2 races rated meaning its having quite a lot of action. Is more/less action a good or bad thing? Interested in the comments of others too, I guess its not necessarily a bad thing providing your Max drawdown is at a comfortable level.

I suppose also comes back to the question what are you more comfortable with:

500 selections over a month 30% SR 20% POT or
500 selections over 2 years 30% SR 20% POT

EDIT: Maybe rather than any horse filtering I need to look at any additional race filtering I can use to improve the results as my horse filtering should all be taken care of in the ratings

I used to be a disciple of selective betting but not now. If you are making a profit go for it and when you have considerable data you may be able to identify weaknesses and prune a little.

Pretty poor day for the ratings from what I can tell glancing at the results quickly, will know more once i'm home and can look at them properly.

Also from what I could tell didn't seem many of the selections fell within the odds parameters besides a few.

SB or Others, i'm interested in your thoughts on something.

Today I was fiddling with the data i've collected thus far looking for a way to profitably lay my lowest raters. After some mucking around and looking at various stats etc I found something that made sense and looked profitable.

Now, so far i've used an overlay range method to make my top raters profitable, but i thought to myself hangon why not just only play my top raters when my bottom raters throw up a lay opportunity.

I won't post the stats etc as i'm still looking into it, but does anyone else take this approach or has tried this approach of only backing horses when a profitable lay system you have, has a play in a race.

The reason I ask is doesn't it basically turn say a 10 horse field into a 9 or 8 horse field for your backing selections? Which you can possibly narrow down further and basically gives you greater opportunity for winners?

I could be way off track with this but it makes logical sense to me providing you have a very good lay system to base it off to begin with.

Thoughts?

SpeedyBen 26th September 2013 05:40 PM

I might have to phone a friend on that one, JB. If the lay that you identify is a short price backing your toppie or overlay probably makes sense to me.
