The optimum rule for advanced primary show jumping competitions is being changed for the season ahead.

In Advanced Primary competitions, riders will incur time penalties should they exceed the time allowed in the first round.

In the second round, however, the optimum time will be calculated by subtracting three seconds from the time allowed and this will create a three second window where riders will not incur penalties until they exceed the time allowed. The winner shall be the rider nearest to the optimum time with the lowest penalties.

In primary competitions, the optimum time will be calculated by subtracting 3 seconds from the time allowed and riders will not incur time penalties should they go over the optimum time.

The rule changes will be available in the 2018 rule book which will be published shortly.
