This mod roughly doubles the speed of arrows, making them "feel" like they have some actual stopping power while also allowing you to hit moving targets a tiny bit easier etc. (nothing too crazy).
It also lets you aim at the dead center in archery contests, since those distances are actually really close so you wouldn't expect any significant arrow drop. 
To get an idea of the actual arrow drop over longer distances, you can look at the first 2 screen-shots.
I'm aiming at (well actually above) the target way back from the entrance of the Rattay archery range in the first screenshot and the second screenshot is where that arrow actually lands.



Reason for making this:

I'm replaying this game after like 2 years, there's been lots of updates etc and half the mods I used to use are no longer working, which made me dive a bit into "fixing" them.

Archery always felt weird in this game, not only the annoying "realistic (khm.. yeahright)" bow sway (I just made another mod to disable that which is compatible with 1.9.6), but arrows just seemed a bit slow coming out of the bow and felt like they lack stopping power.
Even when hunting, it seemed like some of those animals can almost "outrun" your arrows and you'd be better off throwing rocks at them..

Naturally I was trying to find some mod that at least speeds the arrows up coming out of the bow, but I found that the ones I tested merely seem to give you some 'placebo' feeling that they might be faster, without actually speeding them up.

The inspiration came from Arrows go fast by Youcef as I was playing with that mod installed, but didn't really feel enough of a change so I was trying to figure out whether it's not working properly for me or something and potentially "fix" it, but then I realized that the most crucial property of that mod, which is the speed setting in the arrow script does not seem to apply to the arrows themselves and as such I set out to find a different approach.



So what does this mod actually do?

Turns out arrow speed is derived from their power modifier (that you can see ingame as well if you bring up the details on an arrow - screenshots!). 

So what THIS mod does is doubles the power modifier of every arrow in the game, however to compensate for increased damage, it also cuts their corresponding arrow-damage value in half.
This results in your arrows flying twice as fast but doing the same final damage (after calculations) as they did prior to installing the mod, so your "Ranged" damage in your inventory will remain the same despite the individual arrows having half the damage.

I also tried to poke around with the script file that Youcef's mod edits, I really don't see much change, however I think the gravity and mass parameters DO affect the arrows, which (I think) allowed me to give them a bit more of a drop at long distances (not enough imo. but it seemed that if I tweak them further, it will make the arrows feel more unnatural when shot out of the bow with just a partial charge)



Installation instructions:

Either use Vortex to install, or If you download them manually then:
1. you unzip the folder into your mod folder aka. <KCD folder>/Mods/
2. you need to create a text file / or edit it if it already exists called mod_order.txt in that very same folder and simply type the name of the mod on a new line and save it.

(if you have the steam version an easy way to find your KCD folder is to right-click the game in your steam library, select Manage -> browse local files)

So for this mod it should look like: <KCD folder>/Mods/mod_order.txt  containing a line that reads Archerymod
and the folder structure <KCD folder>/Mods/Archerymod/  so when you unzip, you keep the folder as it is
