I find the section titled "Evidence for acceleration" is particularly unclear.

Unfortunately, I and others have found that trying to edit Wikipedia pages, and keep them edited properly, is a bottomless pit. The best we can do is to make it clear here at PF that in general we don't consider Wikipedia to be a reliable source.
