I also expect that, once the complete list of evaluated articles is
published by Nature, we will find that our articles are >longer, so that the error rate *per sentence* might very well be lower in Wikipedia.
A few people seem to have missed this from the website: "All entries were chosen to be approximately the same length in both encyclopaedias. In a small number of cases some material, such as reference lists, was removed to make the lengths of the entries more similar."
