That means that there's about a 2% chance of failing each turn. Over 20 turns, rolling every turn causes that to snowball to 31% chance of failure. The guy with a Stealth of 16 only has a 68.8% chance of crossing that 20 yards silently. Thats the effective skill of 11-12 if we were just using one roll.

I'll try to do the math on what an opposed roll would look like against guys with differing perceptions tomorrow.
I think I see your point...and it becomes more dramatic if you're using a less overwhelming base skill. On the other hand, I have to say I'd think it a pretty impressive feat to approach inaudibly to within 2 yards of someone (after which you can step and attack safely). So I don't know that I have a problem with the odds you're getting.

It seems like distance ought to provide benefits to inaudible movement. Listen modifiers have a clear enough scale, but I don't know what the baseline distance is.
