HAT Effect

Correct per core rules v11

The HAT effect is the chance that when an injury occurs to a player, the head athletic trainer will intervene and prevent the injury.

The HAT effect is debatably the Head Athletic Trainer's most important function, and relies upon the head athletic trainer's Innovation value, or HAT(I). However, as shown in the graphs to the right, a level 10 20/60/20 HAT (HAT(I) = 6) will be only twice as effective in injury prevention as a level 2 30/30/40 (HAT(I) = 0.6): in terms of the HAT effect, it is crucial to have the Head Athletic Trainer position filled with a warm body, but returns for added investment are low.

Note that although these graphs show lower effectiveness in preventing injuries to older players and ball carriers, this is only because of the higher number of injuries sustained by these groups: the absolute number of injury saves per match will remain constant.

The Assistant Athletic Trainer has no direct effect on injury prevention, and does not use his/her Innovation value.
