What method is used when there is no designated scratch time?

The enter to run method is employed when there is no designated scratch time. This approach allows horses to be entered in a race with the understanding that they must be actively participating on race day. Essentially, if the horse is present and the owner or trainer has not opted to scratch the horse by the race time, then the horse is deemed to be participating in the race. This method helps streamline the entry process when there is ambiguity about when scratches should be formally declared, ensuring that all eligible entries maintain the opportunity to run without requiring a strict deadline for scratching ahead of time.

In contrast, the traditional enter method typically involves a more structured timeline where scratches must occur before a specific time. The immediate scratch method, while applicable in certain contexts, deals with circumstances that arise suddenly or require urgent attention, and post-race consideration refers to evaluating events after a race has concluded, which doesn't apply to the entry process prior to a race taking place.
