A member asked us how to back-test the lone likely leader using pre-race data only. In the System Builder, two fields do most of the work, and the video builds the system and reads what it says.

Pace Rating looks at the horse's last three runs: 4 points each time it led, 2 when it race...
This is The Thursday Take — our weekly column on RaceMetrics, where we take the topic racing is talking about and put it to the test against the Proform database. No hunches, no hype. Just what the data says. This week, with the Cesarewitch on Saturday, the trend every preview of the race repeats: b...
Some horses love a sharp, turning track. Others need a long straight and a stiff finish. RaceMetrics now describes every course and trip in Britain and Ireland from Proform's course maps, and puts each runner's record on tracks like today's beside it.The course and trip being runIn the System Builde...

For each we went through every jumps runner at the course in the same month since 2018 and asked one question: did they win more often than their Betfair price said they would? That is A/E: actual winners divided by the winn...
Twenty sires were behind 33% of every jumps winner in Britain and Ireland last season. We put every one of their 13,581 runners through the same test as our jockey and trainer forensics: what did the Betfair price expect, and what did the progeny deliver?

You built a system on the favourite. Roughly one race in twenty, it is not the horse you think it is. The video shows why, and which rule to use in the System Builder for each meaning of "the favourite".

The same owner can race under more than one name. J P McManus, for example, has one name on his British runners and another on his Irish runners, and partnerships and syndicates are often written slightly differently from one card to the next. In the standard Owner breakdown that splits one owner ac...
Twenty trainers sent out 52 or more jumps winners in Britain and Ireland last season, and between them they trained more than a third of every jumps winner run. We put every one of their 11,197 runners through the same test as our jockey forensics: what did the Betfair price expect, and what did the...
