First, i don't have this game (not my style), but please read what i have to say.
I will give you an example. In the game "The Forest" , the activation takes some time to activate (talking about activating the trainer 'F1'), and the rest activating normally, except for the 'F5' that can gets more time to activate.
Another example is, in the game "Watch_Dogs" , all keys are activating instantly, without waiting time.
That makes sense for me, and it's easy to understand, that depends by the game, not by the trainer.
And in my example, the game 'The Forest' can't be compared with the game 'Watch_Dogs'. And also, can't be compared with this one, because of the games engines (or companies).
