Is it really appropriate? When you say that each point is exactly as valuable as the previous point, what do you really mean? In practice stealth acts as a poorlydefined timer for each monster  you have a certain number of turns (modulated by distance to the monster) before the monster wakes up. If you go from 5 turns to 10 turns with your first 3 points, then from 10 turns to 20 turns with your second 3 points, that's not exactly as valuable. Exactly as valuable implies a linear relationship, i.e. the second 3 points should have taken you to 15 turns.
Put another way, why is the utility of stealth plotted (and reasoned about) on a logscale graph?
