    Although I’ve only been posting on here for a week or two, I’ve been reading for a while – I just didn’t feel qualified to contribute.

    I’ve been playing around with my own system for predicting winners and have had a few good days recently, so thought I’d bite the bullet and post my selections on here.

    My spreadsheet predicts a winner for every race, from that I take the top five rated HC and non-HC horses. I’m still playing around with whether E/W or win is more productive, but I’ll still stick my head above the parapet, even though some of the odds today seem a bit scary.
    The information is straightforward enough:- horse, track, time, rating, racetype/conditions, stake.
    I’ve been using discretedata’s idea of pro rata bets, so the stake totals up to £25 for each set of five.

    If I can work out how to present this in a better format, I’ll try and do that next time.

    You have done it now and we shall all be watching.

    I think I can speak for all of us here when I wish you well.

    Sadly the old chestnut of win vs each way has been raised – again!

    Rock & Hard place comes to mind or damned if you do or damned if you don’t, perhaps the results will determin the answer for you but as long as you are happy and in your comfort zone, does it really matter?

    I was chatting to another "old fella’" earlier on this week who happend to mention he bet ew and when I questioned him on the subject he replied "The main target I have is not to lose any money, I hate leaving my hard earned behind and from there the rest takes care of itself".

    Now if that kind of thinking suits you who can argue it is wrong.

    I guess there will be somebody

    :roll: :roll:

    Good luck and don’t forget, we shall be watching.

    Not the greatest start.
    As I said yesterday, I can’t decide if E/W or WIn is the way to go, so I’ll keep a running count for both

    Revised 13:30 GMT.

    Today’s predictions are straight from the box, I don’t know the prices of these horses.

    When I get a bit more time, I want to look at how it rates the previous performances of the horse, and also how well or badly it predicted the previous days races. Obviously there can be reasons why certain horses fail to win other than bad predictions, I’m more interested in why winners weren’t predicted that maybe could have been. I’m also still a bit suspicious that the algorithm favours horses for which I have multiple previous form regardless of how good or bad it was.

    Also, as I get more results to go by, I’ll try and use previous form a bit more intelligently. I have 81 engaged horses today for which I have no previous form and only 15 of them are first-timers, so the information is still rather lacking.

    Hi Darty

    Are you sure you are using the right formula for working out e/w returns ?

    #342598

    I think so.
    e.g
    Russian Flag Sandown 02:20 £2.43 [7/1] 1^8 £25.29
    Wins £17.01 + £2.43 for the win
    Wins £3.40 + £2.43 for the place
    £20.41 + £4.86 = £25.27

    There’s a small rounding error because it’s not exactly £2.43 e/w but 3182/(3182+3295+3282+3306+3292) x 12.50
    which is £2.43168

    Can you give me an example of where I might be wrong other than like that?
    I’ll try and sort out the rounding errors when I get a chance.

    No worries Dart

    You have now started showing the stake which wasn’t there before.
    I can now understand where you coming from.

    Cheers
    Good luck
