Word it as you wish, but basically get 2x tomes if you cleared the whole thing, or half as many if you just skipped optional spawns and rushed to the end. It would be up to whomever implemented it to decide if they want to implement such a thing by lowering the current clear reward or just adding a bonus on top if they take their time to clear.
That's a great idea.

I ran Satasha (story) more than 30 times and only once a experienced player (as tank) asked if people wanted "speed or full" run.

I have no problems with speedruns (but, personally, I don't like much), but I think it's somewhat selfish to do a speedrun when the party has players doing the dungeon for the first time.
