sorry still confused what do you mean by wrap up questions please the area figures for the downloadable documents at least older versions which i have on my hard drive they've substantially revamped the documents recently so this may or may not have changed from nps omit the decimal points from the area figures and if you don't realise that you're going to think that the areas are ten times the size that they are nps documentation discusses the issue but you won't realise it from just looking at the database for more details which again may not apply to the current version of the database you can read the final full section at wikipedia talk wikiproject national register of historic places archive which is where we first became aware of the issue if you go there you'll see that a major participant in the discussion is he's the one who runs so he's been careful to make corrections when problems such as this one come up
