OK, found the answer by myself.

This item has 2 kinds of "stacking":

1. Normal Stacking (Stacking): As shown in description, you will have an 11% attack speed increment per crit strike by picking up the first Predatory Instincts item. Then stacking one more this item will further increase your attack speed increment per crit strike by 1% (not 11%). This does NOT seem to be capped.

2. Attack Stacking (Activating): Triggered by critical strikes, up to 3 times, which will add a maximum 3 times of the attack speed increment to your base attack speed (Initial character attack speed + Soldier's Syringe bonus, etc.) and last for 3 seconds.

e.g. Say, you have stacked 4 Predatory Instincts and activate them twice during an assault (orange strikes above your head). Your total attack speed increment will be: (11% * 1 +  1% * 3) * 2 = 14% * 2 = 28%
