I trained a set 6 times -> Press the play, Piggy in middle, Use your head, Stop the attacker, Defending crosses, Stretch

and 10 times a set -> Pass go and shoot, Pass go and shoot, Slalom dribble, Sprint, Pass go and shoot, Pass go and shoot

The only increase was 5 points in a special ability.
It did not add a single percent to attributes.
