TimeformUS’s Adjusted Fractions Essential Tool for Modern Horseplayers

Are you the kind of horseplayer who refers to sophisticated speed figures to better compare different horses’ official final times?
And are you the kind of horseplayer who likes using the official fractions in horses’ running lines to assess the dynamics of today’s race?

Please read on if you answered yes to both questions.

TimeformUS Speed Figures effectively adjust horses’ final times based on the speed of the racetrack. Official fractions you typically see in other past performances make no such adjustments, so you’re left with the same problem you would have if you used raw final times without also using speed figures to help assess them. Smart horseplayers know that track speed changes. So why on earth should we look at fractions that don’t account for those changes?

This is why TimeformUS offers, and prefers, adjusted fractions over official fractions. By clicking on any horse’s running line in TimeformUS PPs, you can set your preferences for how TimeformUS displays race fractions on the screen.

Here’s how to set the more conventional “official” fractions for each horse and the subsequent display for 2 horses who ran on two decidedly different racetracks–a muddy track on March 7th and a fast track on March 12th.

As you can see, with no adjustments to the fractions, it would seem that La Bella Valeria ran faster at every point of her March 7th race, when compared to Bileaps and Bounds’ March 12th race over a much slower surface.

And here’s how to set the “adjusted” fractions for each horse and the subsequent display for the same 2 horses & the same two races.

With the fractions adjusted for track speed, it’s immediately clear that Bileaps and Bounds ran faster early (and faster overall) in her March 12th race. By adjusting internal fractions for track speed, we are giving you something that is both easy to use and more informative than the raw fractions you see in other PPs.

How we make Adjusted Fractions:

  • All of the factors in TimeformUS Speed Figures are used, including official times, run-up for each distance each race, weight carried, and of course track speed.
  • The fractions for all horses at all tracks are effectively harmonized to a single scale by the TimeformUS Figure Making Team.

Note: Although we prefer adjusted fractions over official times, we prefer pace figures over adjusted fractions.

Here’s how TimeformUS Pace Figures make the game even easier.

    my question also as I notice the times on the 3 NY Main tracks (Sorry FInger Lakes) are quite different. Does Timeform account for the time bias so If I look at a horse who ran a 6F on the dirt at Aqueduct v a horse who ran a 6F at Will Rogers. Also will there ever be a chance that the speed figures for the type of ground (Dirt,Turf,SYN) be separated to reflect that type. I’ve seen speed figures drop as a horse is running from dirt to Turf and Vice versa, yet in my mind it may be for the simple fact that the horse is just not that certain type of hose and should not be “punished” because of a different terrain.


    • Times are adjusted for the racetrack they are run on and converted to a universal scale. It is true horses don’t all have the same ability on different surfaces. We try to reflect that in our speed figures. We aren’t punishing horses, we are measuring how fast they ran in each race. Knowing a horse prefers one surface over another can aid in handicapping.


  2. Yes, exactly. Whether 5f on turf at Fair Grounds or 1 1/8 on dirt at Hastings Park, a 23 is a 23.

    Are the adjusted times equalized track-to-track and surface/distance? In other words, is an adjusted 22-45-110 time at Aqueduct equal to that at Gulfstream?
