Regarding Boomer bitch slaps

About Boomer bitch slapping...

Sometimes when a boomer bitch slaps a survivor, he flies really far away.
Sometimes, he flies really high up.

Is there a way to choose which "flight path" a survivor goes (For example, a tank hitting a car/dumpster/forklift, aiming higher up will make the object fly higher) or is it purely random?

Just asking because sometimes you need the survivor to fly far for a karma slap (Hard rain map one starting point) and sometimes you need it high (Roof of buildings in maps such as hard rain)

It's quite frustrating when you successfully bitch slap a survivor but he doesn't go the intended path and still survives..

 

From my observations in the game, bitch slaps depend on several variables, including the angle from which you slap as the boomer, distance from objects like walls/fences/rails/etc., distance from other survivors/SI/CI, and level of elevation at the time of the bitch slap (both in terms of being up on a roof or building, and in terms of being lower or higher than the survivor like when you are on steps and the survivor is below you or when the survivor is above you on a small ledge or even jumping). There is no way to control the direction of the flight manually.

The most successful bitch slaps are ones done at higher elevation with no impedance to the flight of the survivor in the direction of the slap. If there's objects around or common infected surrounding the survivor, the bitch slap will be a dud most likely. Really high or far slaps are a result of double slaps, where two players simultaneously, or in quick succession, slap the same survivor. I've seen many a double slap send a survivor up high enough to hit the top of the game "box", or ceiling, and come straight down to an instadeath... a glorious sight to behold!
