Report Top Horse Analytics: 01/19/2021 Weekly Statistics in Race Results Posted 3 hours ago How are these statistics produced? At the very start of a year for a track, the previous year's data base is analyzed during which race calculation parameters for future races are optimized and stored in a parameter file. Each week after the start, a track's data base is rebuilt by programmatically adding the previous week's data to the data base and removing the oldest week's data from the data base. Then an analysis is run to re-optimize race calculation parameters. This means that statistics will vary week to week due to the changed data base. During the coming year, THA will sometimes be upgraded with the latest performance improvements prior to weekly processing. This also contributes to the statistics changes seen weekly. After each weekly analysis run, a statistics pass is made to determine which of several hundred conditions are profitable. These are flagged in the track's parameter file. Most profitable conditions are compounds consisting of two or more conditions. When a race is calculated for a track, the best profitable stats from the parameter file for the top horse are displayed on its entry line. You can see some of these races and statistics daily in our Free Pick(s). Questions are welcome such as "Why use an 'always current' data base rather than a static one?". Answer: After years of developing THA, it became apparent that "What have you done for me lately?" also applies to THA horse racing statistics. Other systems may have different answers and solutions.
