Realistic AI Detection (better sneaking)

Note: there is an easier "Lite" version also available.

This is a total recalibration of Skyrim's detection formula, providing much more realistic and challenging sneaking. Enemies will have enhanced sight and hearing abilities, and will search longer when alerted. This mod represents over 300 hours of meticulous research and testing work.

Note: this is the v2.0 "Medium Interior, Medium Exterior" version as hosted on the Skyrim nexus website. http://www.nexusmods.com/skyrim/mods/74355/?

---------- FEATURES: ----------
No scripts. No performance impact. 100% reliable.
AI view cone reduced to 160deg (from 190deg in vanilla).
Ambient light, equipment weight, and line-of-sight are now more important than your sneak skill level. Enemies won't become deaf and blind as you increase your sneak level and perks.
AI can see further and are much more sensitive to light. They can now see better in the dark.
A higher attenuation factor in the detection formula enables AI to see you realistically in very low light levels when very near, without making detection over-powered at further distances.
AI hearing is now the same inside and outside (in vanilla, enemies could hear 2x further outside than inside).
Enemies will search about 2x longer, and will cover a slightly larger area.
The huge difference between standing and sneaking has been reduced to a realistic amount.
AI wall-hacking has been reduced in various scenarios. Example: In vanilla, if you broke line-of-sight in combat, AI could wall-hack you for up to 10 seconds - this has now been reduced to 5 seconds.
"Invisibility" and "Muffle" effects actually work now. In vanilla, enemies could often still see or hear you when using these effects. Not any more.
When an enemy becomes alert and starts to search for you, they get a small boost to their detection ability (to simulate concentration).
If an enemy has not detected you yet and is in combat with someone else, it is now easier to sneak past or backstab them (since all their attention is focused on combat). This effect is stronger in dark environments.
AI reaction time is slightly increased in some situations.
Sleeping enemies have slightly reduced hearing abilities (in vanilla their hearing was the same as when awake).
Enemies will notice dead bodies 10m away and start a search (was 5m in vanilla).
When someone sees you commit a crime, the distance guards come running has been reduced moderately.

Compatible with nearly all mods, but may become unbalanced when used with some dark lighting/weather mods. Uninstalling this mod is 100% safe and automatically restores Skyrim's original vanilla settings.
