Butcherin' Trophy (Leatherface DLC)

Hey All 

First post here  

I Have a Question About The Butcherin' Trophy (Leatherface DLC), where you have to Successfully chainsaw a total of 100 times.

 

I've been told by multiple friends that you just have to charge up your chainsaw and swing away without hitting anything for it to count, However i've been doing it for about 20 games now, chainsawing about 10--15 times a game and still no trophy 

So i was wondering, Do i actually have to successfully hit someone and down them for it to count? did my friends get it wrong? or is it just glitched?

I tried that myself but after a while of aimlessly doing it with no results I just started downing survivors.

I did it by downing 100 survivors.

You have to down 100 survivors! Just stay near the hook (ignore the hate mail you'll get) and wait for them to come to save teammates and use the chainsaw on both the person hooked and the person saving them.
