Progress on Figuring out Stability. Help Wanted.

Hello all,

Recently I've been working on figuring out how stability works on different guns. I decided to start with sniper rifles, and I think I'm getting close.

I noticed that higher zoom snipers recoil much less--for example if you're using a 4.9x zoom scope on a guardian, you miss, and you let the reticle settle, it might be over his head. In the same situation using a 9x zoom scope, it could end up right in his chest.

Moreover, the distance the reticle is displaced after a shot is remarkably consistent...seriously more consistent then I thought my ability to measure it was.

Combining these observations with a fair amount of data I've taken over the past few days, I've arrived at the following chart showing the relationship between recoil and zoom times stability. This might not be the correct model, but so far it seems very promising.

A couple of things immediately jump out:

  • recoil isn't necessarily worse on higher zoom scopes

  • higher zoom can actually make it easier to double-tap, assuming your target doesn't move. Not saying this is a recommendation for using a higher zoom scope, but it, uh, it could be I guess.

 


Too keep going and help suss out the correct model, I could use some help gathering data.

The relevant information seems to be the following.

 

*Name of Gun:

*Scope (or barrel perks if it doesn't have scopes):

*Stability:

*Pixels Left/Right:

*Pixels Up/Down:

*Does the gun have the custom optics perk selected? (This should almost always be no.):

The gun's stability can be found be selecting your perks, then looking it up in DIM or Tower Ghost. It should be a number between 2 and 100.


How to measure recoil. The following is copied from my Tamar-D post:

There are three points which define each bullet's recoil pattern: where the shot is intially fired, the highest point that the reticle reaches, and then where it settles down after this. The first and last are the most important for follow-up shots. If you're having trouble visualizing these, check these out:

The points I want to look at are where the reticle initially is and the final position. One way to do this is to go on patrol and find a consistent starting object to shoot your shots at, then measure the final distance from that.

Usually I take a twitch video (xbox record that would also work well) and then printscreen frames into paint. Yes, this is a really lame method, but it works. There are more sophisticated methods you could use which might work better.

The data I would record from this test would be

Name of Gun: Glass Promontory

Scope: Eagleeye

Stability: 73

Pixels Left/Right: 78

Pixels Up/Down: 149

Custom optics: no

and then I can convert it to the normalized units I've been using. Also note if you're using 1080p images/video instead of 720p. By default Twitch saves in 720p so that's what I've been using.


Right now I'm just starting to figure things out. Once I'm reasonably certain of my results, I'll convert all the units into more concrete numbers. After this I plan to move on to other gun types and also figure out things like recoil direction and how barrel mods affect recoil, etc.

In any case, any help is greatly appreciated. In particular, tests with long range scopes would be super helpful, but I also appreciate help double checking the ground I've covered.

Cheers, gin
