### Dynamic Speed Ratings

When viewing form in our form book software you can see dynamic speed ratings on the race card

**NOTE: Remember that when you change any filter the dynamic speed ratings may be affected because the race/s taken for the ratings may be affected by the filters. e.g. If you used the quick filter to just show wins then all the dynamic speed ratings would be taken from winning form only.**

**dyHA**

This is the Highest Achieved Speed rating the horse as produced in it's career.

**dyMR**

This is the Median Speed rating achieved by the horse taken over all of it's runs. The median rating is the middle most rating of the horses ratings after they are sorted lowest to highest, if there are an even number of ratings after sorting then the median becomes the average of the middle two ratings, if there is only one rating then the median is that rating.

**dyLTO**

This is the Speed rating achieved on the horses latest outing.

NOTE: Remember that when you change any filter the dyLTO speed rating may be affected because the race taken for the last time out rating may be affected by the filters.

This is the Average Speed Rating taken over X amount of races. The X amount or ratings can be changed in the preferences screen, the default is 3 races, so the dyAVG(x) rating would look at the last 3 races a horse ran in and take an average of the 3 recorded speed ratings. If a horse had only run twice then the average would taken over the two races and if it had only run once then the average would be that rating.
