The Win% metric describes the probability that a horse has of winning a particular race. It is designed to be an all encompassing metric that changes depending on a wide variety of factors including which race the horse is entered into, which other horses have gotten scratched, any surface changes, and jockey changes. To make crafting tickets easier, these numbers can also be added together when using multiple horses.

This is in stark contrast with other products' rating numbers. Experienced handicappers are often confused on how to use this number because they're so used to existing ratings. Let's run through an example with two races.

In race 1, we have Decelerate with 50%, Gun Walker with 25%, and Egyptian Pharaoh with 25%.
In race 2, we have Mucho Macho Woman with 50%, Ghostsaver with 10%, Pleasantly Imperfect with 10%, Tizthen with 10%, Cat Detective with 10%, and Skip Back with 10%.

## Chance to win

The main benefit of the EE Win% metric is that all the work is done for you to give you one number that describes how likely a horse is to win, regardless of who else is in the race. A 50% horse has a 50% chance of winning regardless if she's running against a 25% horse or a 10% horse. We have done the math to show that this number is accurate. If we grab a hundred 50% horses from a hundred different races, about 50 of them will win.

Handicappers familiar with other products' ratings will often ask something like "How much more likely is Decelerate to win than Mucho Macho Woman?" This question makes sense for other ratings because most of those ratings have no meaning by themselves. They're only meaningful when you compare two horses, and only if you have a chart that shows you how like a 98 horse is to beat a 89 horse. We have done all that work for you can simplified it down to one number that has a meaning. The answer is Decelerate is just as likely to win as Mucho Macho Woman because they both have 50%, even though they are facing very different competition.
