When determining the base saves (high, low), why was the high save made [(Lv/2) + 2] while the low save was made [Lv/3]?

Why not have the low save [Lv/2] or [(Lv/2) - x] (where x is 1 or perhaps even 2), to make things more symmetrical? Or, if they wished to use thirds, perhaps make the high save [(Lv/3) + 2]?

There are so very many possibilities, so why were the two chosen (for high, low saves)? Was there a particular reason? Did they just seem to "look about right"? Was there a 2ed tradition in need of following? (As far as I know, 2ed did not even have save progressions with level, so the latter is unlikely, I think.) Was this a hold over of another system the d20 was perhaps based upon? (Was the d20 system based upon another, for that matter?)

I would hope that there is a valid reason, perhaps mathematical, or at least logical, for the selection, but I am curious as to what it might be.

Did they just seem to "look about right"? That's how I'd do it, actually. Given the DCs a character is likely to face at each level, I'd determine what save bonus I'd want that character to have (basically, how much of a chance to succeed or fail). Starting with those numbers, I'd look for a nice, easy formula.

I'm not saying that's what the designers did, but I think it's actually quite a good way to do it.

Propably to have a significant difference. Since its looked up on a chart, I dont figure that having them be comparable to each other in the math, was a major worry

Reread the books. Saving throws have progressed since the very first D&D book.

D20 is based on a ton of games, and has taken bits of them along with it. I cant think of many rules in D20, that havent been used before, somewhere else.

With game design, often, something is the way it is, simply because thats the way someone wrote it down as, and noone had a reason to change it.
