For articles created from Jan 1 2007 till Sep 13 2007, I calculated the time difference (in seconds) between the first and the second edit made to an article. This roughly represents the time taken for an article to be reviewed by a second editor. As usual, deleted articles are not included in the gathered data. Also, only pages from the main namespace where considered.
The minimum time difference was 7 seconds, and the maximum was 2320154 seconds (26 days). As the data was very skewed, mean and standard deviation could not represent the data usefully. Therefor, the median of the data was calculated which was 532 seconds (8 minutes 52 seconds).
The same analysis was undertaken for English Wikipedia, as the most edited sister project. The results where very similar: The minimum value was 7 seconds, the maximum being 2497053 seconds (28 days); median was 536 seconds (slightly higher than Simple English Wikipedia, but statistically insignificant).
Based on this information, it can be estimated that our editors are as good in reviewing newly created articles, as those of English Wikipedia. It can be later reconfirmed, by changing the codes used for calculation of these measures, in a way that the time difference between the first edit by the article creator, and the first edit by a "named" user could be calculated.
