    The formula goes something like:

    1. Assess the last two form ratings:<br>    1st = 5 pts<br>    2nd = 3pts<br>    3rd = 2pts<br>    4th = 1pt

    2. Apply points for C and D:<br>    C = 1pt<br>    D = 2pts<br>    C and D = 3pts<br>    CD = 3pts

    A maximum is 13pts, and Clive provided evidence about backing all maxmium rated horses for a profit.  I did a little research last night, and this formula has a good strike rate, but returns a level-stake loss at SP in recent years.

    There are other factors to consider such as whether the horse has proven, progressive or promising form.  For the time (1986), the book "Be a Successful Punter – With Fineform as your guide" is an interesting read, especially if you can find a copy like I did for £4.

    I did speak with someone who said that the formula had evolved, and included points for the paper rating and BF as mentioned in my previous post, but I cannot find any evidence for this.  From memory, I believe;<br>- top 3 rated by the paper were given 4pts<br>- first 3 in the betting were given 3 pts

    Maximums are therefore 20pts.

    Thanks, lfaw

    Seems a reasonable approach for anyone looking for a very quick way to make a selection, although it has obvious limitations.

    Including the top three rated horses and top three in the betting as qualifying for points seems sensible and logical. I have seen systems that are less sensible and logical than this, some of them costing money. It would be interesting if someone could monitor this method over a set period, although I suspect it is not sophisticated enough to make a profit.

    This is probably the reason it is no longer advertised or promoted.

    The Effect of the Draw

    As far as my ratings are concerned the draw can make a difference of 6 points (-3 to +3) between horses.

    It isn’t always easy to apply this factor to a particular race because of the variability of field sizes, changing going and watering policies.

    There are a number of courses where there is a natural bias that seldom varies, irrespective of the going. Examples are Chester (Low), Beverley (HIgh in 5f, High in 7/8f), Catterick (Low in 6/7f).

    Apart from my own experience, I usually check the track bias with:

    1. Racing Post- Topdraw gives a course description and calculates the bias in lengths based on fairly recent data. Reasonably accurate but sometimes gets it horribly wrong when there is a sudden reversal of the bias. You have to excuse this because the deadline for the RP doesn’t allow last minute changes to be flagged up.

    2. The Racing and Football Outlook (RFO) give an updated view of the effect of the draw (usually on page 4) every Tuesday for the coming week. They have a resident draw expert, Graham Wheldon, who also does some of the spotlights in the RP. Graham is a very good judge and doesn’t often call the bias incorrectly.

    3. If the meeting is more than just the one day, the previous day’s results are worth a perusal to see if there is any obvious bias.  With one day meetings you have to rely on previous history unless you are at the track/watching on tv. However, your bets may be already on based on your assumptions, so it may be too late.

    Once you have decided there is a definite advantage in the draw, it has to be quantified.<br>My rule of thumb is:

    up to 5 runners………No points<br> 6 to 10 runners……1,2,3 (+ 0r -1, depending on high or low) and highest 3 in the draw, the same.<br>11 to 19………lowest and highest 3 (+ or – 1,2, or 3), depending on degree of bias. <br>20 or more runners is the same as above except that I’d be + or – 2 or 3).

    e.g 16 runners  very strong Low bias e.g 5f Chester

    Drawn 1,2 3    +3<br>           4,5,6    +2<br>           7,8       +1<br>           9,10      0<br>           11,12    -1<br>            13,14  -2<br>           15,16   -3

    A few points.

    If a well drawn horse misses the kick, and it is a front runner, it often cannot get back into the race.

    Horses coming across from an unfavourable draw to contest the lead can cause mayhem as well as using up vital energy in having to be hard ridden so early in the race.

    Not many(relatively speaking) horses enjoy racing alone or in a small group when they are aware of a much larger group in the vicinity.

    The most important factor in a race for most horses is that they obtain a clear passage when making their challenge. If momentum is lost it is difficult to regain it especially if the early/middle pace is slow.

    The above points can be closely linked to the horse’s draw, but chance (unquantifiable) plays a big part.  

    Finally, I see no reason why the draw shouldn’t be given more or less preference in any set of circumstances, but I’d be very surprised if it made more than about 10lbs difference unless one side of the track was firm and the opposite side only good to firm. If the bias was any bigger than that, the Clerk of the Course and groundsmen are failing in their jobs.

    As from today, I’ll be posting occasional selections (derived from the method outlined at the head of this thread) on this part of the forum rather than the betting tips section. This is so that I can keep a running total of profit/loss and try to deal with queries and comments as they arise.

    A profitable day yesterday,+ 72 pts from stakes of 110 pts. <br>Today’s selections are from Ascot, where the racing is very high quality  – I haven’t really looked elsewhere, except for my weekly stab at the Scoop6.

    Thanks Dave. Winners have been easy to find over the last three days. It won’t always be so. My long term profit target is between 5 and 10 per cent, and I think that is attainable using basic form ratings plus about half a dozen additional positive factors.

    Yesterday returned a profit of 129 from 170 staked.

    Quite a few selections today which qualify being rated at least +10, and also 3 points clear of their nearest rival. The staking method is between 10 and 50 points  depending on the horse’s ratings and the scores of its opponents.

    +25 or more and +5 or more ahead of nearest rival is a maximum 50 pts or 20 pts ew

    +20 and +5 or more ahead is30/40 pts win or 20 pts ew

    +15 and +3 or more ahead is20/30 pts win or 20 pts ew

    +10 and +3 or more ahead is 10/20 pts win or 10 pts ew

    maximum bet in maiden races is 10 pts win or ew.

    Today’s selections:

    There is some excellent racing today, but the ratings method I use indicates that not many horses stand out as betting opportunities. In the Cheveley Park, for instance, the entire field is covered by only 5 points, so I wouldn’t be surprised if there was a shock result.

    Today’s selections:

    Goodwood  2.05 Succession 105 (+22) 30pts win- 3rd<br>Newmarket 3.00 Diktatorial 129(+17)   20pts win – won 3/1<br>                   4.05 Clueless 104(+10)      10pts win – 3rd<br> <br>Stakes 60pts  profit 20pts

    Thanks LFW. The ratings are working out well, although I would expect the profitability to level out to around 5 to 10 percent. I would be happy with that. The turf racing is coming to an end and it wii take a while before the AW form produces useable speed ratings on Wolverhampton’s new surface. Also, I only look at grade D and above, so betting opportunities in this sphere are necessarily limited.

    The jumps provides betting opportunities but because of movement of horses between NH flat, hurdles and chases, not to mention horses moving over from the flat (turf and AW), the form is not so easily interpreted. However, flat form is usually overvalued when translated to the jumps, so good value is often available for those horses with proven jumps form and this helps to keep profit levels up.

    There is a very long list of qualifying bets today, no less than twelve! It’s a day when any ratings method can look a bit foolish if it ends up with a (not inconceivable) blank. Anyhow, keeping the faith, here goes:

    No Cigar yesterday, but no egg on face either. The quality racing today is at Longchamp – I was there in 1970 when Sassafras just pipped Nijinsky. It’s difficult to get speed ratings for some of the runners, so it isn’t possible to rate them properly. In the Arc, Grey Swallow has the best recent form (last 60 days) and in the Prix De L’Abbaye, Patavellian and The Tatling come out equal top, but none of them qualify because of the lack of information about their rivals.

    Today’s qualifying selections:

    Uttoxeter 3.40 Made In France 143(+11) 10pts win 2nd<br>Market Rasen 2.40 It’s Definite 121(+11) 10pts win        won 13/8<br>                      3.50 Dabus 131(+15) 10pts ew unpl<br>Kelso             4.00 Gianluca 133(+17) 20 pts win unpl

    There were no qualifying races (Grade D or better) at Plumpton, and at Pontefract no horse was 3 or more points clear in the ratings, a necessary stipulation to qualify as a selection.

    Some very short prices, but this ratings method makes no judgements on that score, nor does it filter out odds on qualifiers. I have some long held opinions on value when betting, but I’m trying to show that this method can produce between 5 and 10 per cent profit at SP, regardless of the odds and without getting on at early morning prices which may not be generally available. I’ve noticed that the majority of these selections do shorten in price, often close to the off because they are backed by people using computerised ratings systems who are using similar data and parameters. Before they place their bets they need to know how the market is moving.
