It helps to train your pets so they place better in the events. I still train "all" my pets so they place better in competitions. Some times my best trained doesn't place well in an event they placed 1st in, in the past. I also enter "all" events throughout the month, I do not concentrate on any one in particular. I watch to see how my main trained pet places; however, I found no trend. It seems to be random, and whomever they are competing against in the event (who could be better trained), just like the older olympics did. So, keep training, keep entering as often as possible.
