Wow, great work! Again, trying to keep things very simple for both my understanding and purposes of the wiki (while still linking to this discussion for those who want more detail), is the below proposed revised wiki text accurate as far as it goes? One area I'm still unsure about is how exactly the "half base speed/playerMotor.IsMovingLessThanHalfSpeed" etc. language translates to the in-game controls of crouching/sneaking/walking/running, as well as whether crouching (assuming crouching is also considered less than or equal to "base sneak speed", which I believe is in turn equivalent to "half base speed"?)/sneaking is advantageous in terms of maintaining stealth over walking/running in the situation where the enemy has yet to "see"/"hear"/"encounter" you - so the final two sentences in the below proposed language may or may not be accurate. It also appears "ambient light" isn't actually a direct factor, so I've tentatively removed that prior language. Finally, I'm a bit confused about the terms used and the order of the enemy "seeing"/"hearing" vs. "detecting"/"finding"/"encountering" you in your description. However, without complicating this even further, I'll just let you critique the proposed text if you'd be so kind, suggesting any specific corrections you think necessary:
Whenever you approach a creature and enter its detection range, your Stealth skill is automatically checked to determine whether the creature successfully detects you and (if hostile) engages you in active combat. In addition to your Stealth skill value, other factors affect your chance of successfully avoiding the creature's detection, including the creature's Stealth skill, your distance from and location in relation to the creature, and your movement speed. If the creature has initially seen and/or heard you, leaving the creature's sight and hearing range and then moving more slowly - i.e. by crouching or sneaking instead of walking or running - will enable you to continue to attempt to avoid detection, while walking or running will result in detection by the creature. On the other hand, if the creature has not yet seen or heard you, you may continue to attempt to avoid detection while moving at any speed.
Thanks for digging into this other issue as well! My layman's read of the code you copied indicates shields are also subject to the same display discrepancy as other armor pieces, such that their armor rating values shown in the player paper doll as applied to the various body parts must be multiplied by 5 to determine the actual values used in the game's armor calculations, but you would know better here.
