I'm trying to increase the health gained per hour of rest. I've found mention of a stat call sHealthPerHourOfRest in the Menu section of Game Settings but can't find any actual number to change anywhere.

It would be under the Gameplay tab of the (Game) Settings menu. All that I can find that sounds relevant is fSleepRestMod. Morrowind Scripting for Dummies declares it is unused (and not what it might govern). It has an initial setting of 0.3. You might play around with that value to see if it does anything. I would be surprised that this would be hard-coded, but I have not found anything other gamesetting that appears more promising. Good luck.

If you can't find a game setting that controls the health regen then you should be able to at least add to it using this script. I haven't tested it yet but it should work. However I'd definitely suggest using a game setting over a script to get the job done if possible.
