All the research can be found in this thread.

But, to make your life a little easier I'll break it down here:

Campaign:
- reduced recon ranges
- time 2x slower
- bonus: Nato icons for the map
- increased time between events

These are purely my personal preference. For ex. with recon ranges I think the game gives you too much information about where the enemy is - there's no uncertainty common in submarine warfare - that's why I changed it.

Movement:
- increased angular momentum for all US subs

Basically, I starter by comparing 688 with DW. After achieving roughly similar results I based values for other boats on displacement difference (for ex. displacement ratio between Narwhal and 688 is 1.288, so for Narwhal I multiplied LA's values by this number).

- MAD detection range reduced to 400

This paper: http://calhoun.nps.edu/bitstream/han...pdf?sequence=1
page 42 (took the middle value for 60 latitudes)

- Sonobuoys passive sensitivity reduced to 25
- Dipping sonar sensitivity increased to 32

Based on gut feelings with comparing to DW

- decreased TMA rate for player and AI to 0.7

Personal preference and gameplay reasons (I think TMA's are too quick in base game)

- new warhead sizes for all torpedoes

First, I took warhead sizes from this website: - new warhead sizes for all torpedoes
Then I calculated their TNT equivalent. After that I replaced the Mk48 warhead in the game with a real value and did some tweaking so you need 2 torpedoes to kill Sovremenny but 1 for most submarines. Turned out it's 0.83 of real value. Then I multiplied real values for all weapons by 0.83 and put those in the game.

- new noise values for all torpedoes based on speed and propulsion types

Here's the spreadsheet that contains all calculations: https://docs.google.com/spreadsheets...gid=1880361556

- decreased sensor angle for Mark 48 to 60.

Gut feeling based on playing DW

- decreased acquisition range for Mark 48 to 1600.
- new acquisition ranges for all Soviet torpedoes based on real values

Mostly, denis_469's forums (http://sovpl.forum24.ru/?1-4-20-00000051-000-20-0#020) and conversations in this thread.

- decreased lifetime for knuckles to 3
- decreased noise (effectivnes) for knuckles to 50

Personal preference

- decreased player hull strength to 0.65
- increased AI hull strength to 1.25

This to account for different hull design (single hull for us, double for Soviet) - basically this means that any torpedo except UMGT-1 will kill any US sub.

- increased combat repair time to 2.5

That's also personal preference
