Answers to EMAIL questions from serious users
 
  1. Because we list as a win contender any horse with a "10%" or higher chance of winning the race, we know we have a good list of win contenders. TVL "fair odds" represent each win contender's chance of winning (win probability). Valuline can either be used as a "stand alone" method to discover and bet on good overlays, or as a "bench mark" used in conjunction with your handicapping.

  2. It makes no sense to us to present a fixed number of win contenders in each race, as many handicappers do. Each race is different, and our 10% qualifying rule means that races MUST necessarily have differing numbers of win contenders. Some races have only one or two. Some have as many as five or more.

  3. ALL our Betting Strategies are recommended, having passed the required testing.

  4. The betting decision as to the acceptable minimum amount of overlay should be an individual user's decision. We define a "negligible overlay" as track odds less than 25% above TVL fair odds; a "marginal value bet" as 25% to 49% above; a "good value bet" as 50% to 99% above; an "outstanding value bet", and also a "Longshot/Monster value bet" as 100% or more above TVL odds.

    NOTE: The degree of overlay determines the bet, not the horse's relative position on the list of win contenders. The larger the overlay to TVL fair odds, the better the value bet.
  5. Late program scratches of win contenders require a re-calculation of TVL odds.

    Here's race #2 from Hollywood, June 2, 1999 as an example:

    DELRAY DEVIL had a 29% win probability, which is TVL odds of 5/2. PROFIT RECORD's win probability was 20% or 4/1. LESGARDIENS 17% = 5/1. NORTHERN CALL 13% = 7/1.

    PROFIT RECORD (with a 20% win probability) was a late scratch. To re-calculate the win probability of the remaining contenders:

    DELRAY DEVIL is now 29%/1-20% = 29%/.80 = 36% = 9/5

    LES GARDIENS is now 17%/1-20% = 17%/.80 = 21% = 7/2

    NORTHERN CALL is now 13%/1-20% = 13%/.80 = 16% = 5/1

    NOTE: For conversion of the win probability into TVL fair odds, either do the calculation (for DELRAY DEVIL 1/.36-1 = 1.8 = 9/5) or simply USE THE FOLLOWING TABLE:

(Scratches of entry-mates. Since we provide a combined win probability for entries, the scratch of any part of the entry reduces the win probability of the entry as a whole.)
  1. The problem with single-factor analysis. The outcome of a horse race is a combination of MANY factors. All of these factors must be "measured" in order to determine the relative capability of a contender -- to rank the horse in the order of its chance of winning and fair odds. The recent popular "fad" of single-factor analysis has led to handicapping errors: the bettor's emphasis on the factor (for example, trainer/jockey "angles") leads to betting on the wrong horse. Trainer/jockey angles are generally based on too small a sample, which is frequently transitory. Trainer x uses jockey y on 9 mounts and wins 3 (33%). (They still have lost together 67% of the time.) If in the next 18 mounts they don't win together (which is very possible), the win percentage drops to 11%, which is average.

  2. Late jockey changes. Our past performance data INCLUDES those jockey (and trainer) changes that are known and appear in the track program. This ,then, is more complete than that which appears in "overnights".

  3. Each track's Valuline report is issued daily throughout the race meeting. The Exotic Key Plays report and the Top Ten Value Bets Report are issued daily, except when there are not sufficient plays.
