This is a work in progress 
It does not give you permission to distribute any patches made without my permission.

This guide assumes you have experience with modding and xedit. 
Please don't try and follow this guide without any knowledge of what you're doing.

Please note, this is only how to change the recoil values in general. attachments will add, subtract or multiply the values below. This should usually be fine, but if the mod author has done some obtuse values it may result in unintended recoil behaviour.

fo4edit

Step 1: open up fo4edit with the "Recoil Overhaul.esp" and ALL esp's for the weapon you want to patch.

Step 2: in the esp's you want to patch, look for "Aim Model" If it doesn't exist no patch is needed.

Step 3: In the aim model section, look for the weapon you want to change. It should look like this.

DNAM - Data
Cone of Fire - Min Angle                      |  x.xxxxxx         |  x.xxxxxx
Cone of Fire - Max Angle                     |  x.xxxxxx         |  x.xxxxxx
Cone of Fire - Increase Per Shot         |  x.xxxxxx         | x.xxxxxx
Cone of Fire - Decrease Per Sec         |  x.xxxxxx         | x.xxxxxx

ect... x.xxxxxx being whatever value it shows.

Step 4: Here's what you should change in your patch. again, please know what you're doing.
These values are x.xxxxxx to x.xxxxxx the value in the middle is what I recommend, but those values are safe to use depending on your own preferences. e.g 12.000000 to 14.000000  My recommendation would be 13.000000.

For Assault rifles

For a vertical recoil pattern (AK style)
