I have found many caches where the terrain/difficulty ratings are either much higher than I experienced, or much lower. Setting such ratings is very subjective. I think it would be a good idea if they allowed users to rate what they think the difficulty/terrain should be after finding it. So when you log a cache as Found It, there could be a drop down for a difficult and terrain rating. And then the average user rating for terrain/difficulty could be shown at the top of the main page representing all those who found the cache. I think this would produce a more accurate rating overall.
