AD&D Saving throw modifications

Okay, because I am a loser, I spent more time thinking about the saving throw problem after I wrote the 2nd edition of the rules hospital. So I decided to just make it a separate section since sometimes I will be awakened in the middle of the night by phantom ideas for revising saving throws and using my indomitable discipline, I will say, "No, Nealok," (I call myself Nealok, too.), "you already have a section on saving throws; you don't need another one."
      But I was tired of denying my true self, so I made this page. Without further ado, here are the ideas.

• First of all, see the Nealok's AD&D Rules Hospital Vol. 2; I am big on the averaging things is still a good idea, I think.
• Take the average ability score of the character, the general composite for the character's overall abilities, and roll 1d8. For 1-4, subtract it from the average; for 5-8, add it. Using some method, preferably the one I suggested for point-based advancement (because I'm the man), or some other method determined by your DM, add points to this stat, which I have named [drum roll} Luck. The reason behind this method is that essentially, all the saving throws are related to a character's capacity for luck, and who knows what that is based on. Still, it would suck a LOT if there were nothing any character could do to advance this number, so that is why I suggest characters be able to add to it, reflecting their advanced experience. This would also be a good number to which to add a temporary point for exceptional role-playing.
• Just roll an existing stat, probably Intelligence, Strength, Dexterity, or the Willpower or Perception stats I suggested in an earlier Rules Hospital.
