Here's a tip - specifics when explaining your problem work wonders. Seriously. I'm a developer, albeit not a game developer, and it's *much* easier to understand what people mean when they explain a problem using a specific example rather than general complaints. Of course what you wrote is clear to you - you wrote it and know what you are trying to say. The rest of us aren't mind readers, and your post is a bit rambling.
From what I've seen so far, archery skills don't show a hit percentage. If you use something like Ricochet or a special arrow, they act like spells. You hit whatever it shows you are going to hit.
If you're talking about normal ranged attacks, and you think the percentage is wrong, look at the following: Offence rating, distance to target, character's perception (if to hit is affected by range penalties). If that number looks wrong compared to what you're calculating your to-hit should be, look at what the to-hit is for a melee character on that target. Also make sure you don't have any negative modifiers, like ranged power stance active.
So I'm looking at the starting ranged companion right now, and she has a crappy 53% chance to hit something 2.9m away. Her Offence rating is only 82 though, and at 2.9m away with a 6 perception, that's ((2.9 - (6 * .4)) / .2) * 1% = 2.5% penalty. So I would've expected a ~80% to hit, based on the info I see on the wiki.
The problem there is after doing some testing, I see she's showing a 53% chance to hit on everything within 9.2m. After that, it's a 1% drop for every .2 meters. So the wiki fails on that (I'll have to fix it later), but at least pretty clearly her base chance to hit is 53% when not affected by range.
Next I look at my melee character. She only has a 59% chance to hit. Her Offence rating is 88. Hmm. 88-59 = 29. 82-53 = 29. It looks like this enemy has an Defence rating of 29 (modified by difficulty - on normal it's only 19).
So in summary, you don't have a 100% chance to hit with ranged attacks when an enemy is standing next to you for the same reason you don't have 100% chance to hit with melee weapons.
If that's not what you were complaining about either, then please consider working on your communication skills.
Oh, and the chance that your reading comprehension exceeds mine is miniscule, but if it makes you feel better to think otherwise, then good for you. I'd normally say that's yet another example of how ignorance is bliss, but you seem to be anything but full of bliss. ;)
