Is it alright if I give the spam punishment in such a way that it is always in the positive?

e.g. on a 10-second CD ability, with a stacking mechanic (on a different ability) that goes up to 5 times, 'the cooldown of this ability is reduced by 5 seconds (-1 per stack)'; over a 5-second CD ability that says 'the cooldown of this ability is increased by 1 second per stack'.
