[QUOTE="Celebrim, post: 5864231, member: 4937"] Carefully thinking about the numbers reveals that they are pretty much useless though, especially given how many factors and calculations are involved in using the system as given. A few sniff tests will suffice to prove this. The table gives that maximum spot distance for open grassland at 720 feet - about two football fields end to end with the ends zones. This is for want of a better term, rubbish. With enough time to scan or a bit of luck, you can spot a moving person or animal on open grassland at a distance measurable in miles. Two parties walking across the open prairie would sight each other well beyond the average person's effective rifle range of 400 yards. Particularly keen eyed pilots have been known to spot other airplanes beyond the effective range of most radars. What we would really like to know is how much concealment was on average provided to someone who wasn't stationary at a given distance depending on their size and the available terrain. Low brush or high grass might not provide a human any appreciable cover unless they lay down and crawl, but its easy to see that they'd probably provide a snake 100% or nearly 100% concealment until it was quite close indeed. And we'd also like to know exactly how much of a bonus to hide was provided by a given level of concealment short of 100%. One way to look at this is to note that 3/4 cover reduces your profile to the same extent that being a smaller size class would, so the bonus to hide for 3/4 cover must be around +4. Similarly, 95% cover or concealment - such as a arrow slit or a thick mat of vegetation - must provide around a +8 bonus. A tiny peephole or a keyhole, to small to attack through or even have a wide field of vision might provide a +12 bonus. A fine sized beetle on the other hand, would get no such benefits, since its already about as small as the peephole. Instead, 95% cover or concealment for it might equate to crawling on the backside of a curtain. [/QUOTE]
