Not that I have ever looked at what your quoting,
But in a lot of instances a logarithmic scale is used for scores above 100 and linear below, this is what is employed for something like Beyer's scores.

woof43 interesting you say that, when I was looking at how fav rankings compare between field sizes I found that the prices fit pretty closely to both exponential and logarithmic scales. If you plotted the rankings and prices over time for field sizes i'm guessing you'd be able to come up with an equation that estimates the prices closely to R&S P$, if you want to go to that effort i mean.

Been there, done that, but can't quite agree. Sure the charts differ, but I think it's more a duplication of this scenario: 6 blokes go to the club for a Sat punt. Natural selection (Fibonacci) will probably see 3 blokes back the fave, 2 the 2nd and 1 the 3rd. It's just nature and it produces a log curve. Look at my thread on the Golden Number 1.618. Using that ratio alone,is the almost the exact sequence for rank strike rates.

If you wish to make profits short term/long term whatever, look no further than these 2 lines. It's all you need to know.

That's how i learned, from the help i got.

A Tale of Two Cities
 

No this isn't a Dickens novel, it's Beaudesrt 11, and the two different tales of probabilities.

It's useful if you plot a chart from excel before committing to a betting decision. You know, "A picture's worth a..."

The blue line is the good old predictable Betfair back price. It always starts around 30% and follows the tried and true path to oblivion, as that's what everyone expects, it's inherent in humankind.

The red line is the rating courtesy of R&S . Wow!...the 1st fave is looking like it'll fall over, and did (2% ~ 33%). The 2nd fave won but not a value Back bet (15% ~ 28%)

Chart of the Day?
 

Chart of the Day goes to Geelong #4. Jive Music got up and won at $85. Why isn't that a surprise....coz it was rated at $6..??
