The experimentation must verify three aspects of the innovation:

1) the dimensions of the fields added to the traditional door.

2) the score to attribute to every field.

3) the modifications in the development of the game for effect of the greater dimension of the target.

For the first verification they are preferred 7 players team because, in absence of outside game, is much more frequent shooting to net.
Once the dimensions of the added fields are calibrated, the experimentation will have to be moved in the to 11 players team in order to verify the modification of the psychological and tactical aspects.
